Which is making your baby cranky – teething fever or sickness? How to tell

Is your baby actually sick or just teething?

It doesn’t matter if you are first-time parents or think you’re old pros; when you have a cranky baby, you think the worst and go through the checklist of everything that could be wrong. Sometimes it’s as simple as gas or a wet diaper, but otherwise, you’ve checked the usual suspects, and the cries haven’t stopped.

When your child is an infant and they have a fever, it usually means one of two things — your baby is sick or is cutting a tooth — and they both could come with a warm little forehead. Here’s how to tell if that hot forehead is a teething fever or a sign your baby is sick.

The symptoms and how they cross over

Symptoms if your baby is sick

A sick baby makes the whole house miserable. That first sneeze or cough might get a little cute reaction, but by the second one, parents go into doctor mode.

Common sick signs

  • Consistent cough
  • Runny nose
  • Sneezing
  • Diarrhea
  • Increased grumpiness
  • Extra sleepy (get those cuddles)
  • Warm to the touch/high fever

Symptoms if your baby is teething

Teething is not fun for the baby or the parents. But, to be fair, having a tooth rip your gums open would make anyone extra cranky. 

Common teething signs

  • Chewing on everything (clothing, hand, toys)
  • Excessive drooling
  • Touching or rubbing their face and head more often
  • Not eating as much
  • Not sleeping like normal
  • Increased grumpiness
  • Warm to the touch and low temperature

The crossover of teething and being sick

Where things get confused is a baby will have symptoms that could be either cutting a new tooth or getting a cold. The fun for you as a parent is to figure out which it is.

But not every baby is the same. Some teething babies have a runny nose and some sick babies don’t want to sleep. Since babies can’t talk and won’t be able to tell the parents what the deal is, they need to inspect that baby a little closer.

How to tell if it’s teething versus sickness

Most parents go straight for the symptoms to mean a cold or other sickness. All those new people wanting to see and hold the baby bring all kinds of new bacteria and germs. Plus, no parent wants to see their helpless baby sick, so it’s where the mind goes first.

How to check if your baby is teething

Every baby will cut their first tooth differently and at a different age. Though around the 6-month mark is when those adorable front teeth usually start to pop up, it could be as young as 3 months old or as late as 12 months old before your child has teeth.

If your baby has been experiencing teething (or sickness) symptoms, the best way to figure out if it’s a tooth is to get up in their mouth. You could use the flashlight on your phone and have a really good look around in there. An obvious eruption of a tooth where you can see it is the dead giveaway you are looking for.

If you don’t see an actual tooth, prep a finger for a potential bite, because you will have to poke around in there. If you feel any bumps or if your little one screams out or bites you when you hit a certain spot, they are teething.

Why knowing about the fever is important

An increase in crankiness and a fever could mean either, but the fever is a good indicator of which it is from the type of temperature your baby has.

The temperature difference

Teething brings about a temperature of up to 100.4 degrees. And anything over 100.4 would indicate your baby is sick. A low-grade fever alone won’t point to only teething, but if you have a baby with a small fever plus drooling plus being irritable, you will have a tooth in that little mouth soon.

If your little one is only a few weeks or months old and has a fever with symptoms like coughing or sneezing, they could still be sick and not cutting a tooth yet. As a parent, you get to play detective and figure out where the clues take you.

How to treat the fever

Whether from teething or a cold, the fever and other symptoms need to be treated to make your bundle comfortable. Adults all feel like the world is ending when we have a fever, too, so we shouldn’t be mad at an infant for it. Following the directions on the Tylenol bottle is a good place to start to get their temperature down and pain under control. If you aren’t comfortable giving them medicine due to your baby’s age (or whatever reason), never be afraid to ask the pediatrician what they recommend — that is what they are there for.

If your tiny human has a fever, check their temperature with a thermometer so you have a good handle on what the situation could be. A low-grade fever points to new chompers, and a higher fever points to a sick baby. A fever alone won’t tell you either way, but the level of fever coupled with additional specific symptoms will tell parents what is going on with that cranky little person. Teething fever or sickness — either way, your baby is going through it and needs extra cuddles and patience.

We love these boys’ fade haircut ideas (and your kid will, too)
From toddlers to teens, a boys' fade hairdo could be the new style your child loves

We get so excited about all the options for haircuts for girls, that sometimes the boys' styles get overlooked. A clean, neat haircut can raise confidence and show off his adorable face, which is slowly changing into the young man he is becoming. Don't worry — no bowl cuts here, just popular and unique cuts that use the fade to bring out your child's personality. Find a boys' fade haircut to fit your child's style or go for something new to see how it fits when you give these cuts a try.
Basic boys' fade haircuts

Classic short undercut
One of the most versatile and easiest fades is the undercut. It looks cool, is easy for parents and kids to maintain, and offers a bit of flexibility in styling. If the top is shorter, you could spike it up or style it to the side if the hair is left a bit longer.
Taper fade
If your child wants something a little more basic but can look put together in just a few seconds of styling, the taper fade leaves you with a few options. It's a classic cut but with an effortless edge to it, where the fade starts at the bottom but seamlessly blends into the hair early on, leaving the rest of the head to be styled how you want.
French crop
This cut is for the child with a little more edge and personality. It's still a low-key cut with little maintenance to style it, but its endless looks are modern and fresh. Start with the classic French crop cut, and then add a high fade to the sides and back. This will give more attention to the top, which you could leave longer, slick back, or cut shorter and spiked.
Faded buzz cut
Every boy in the '90s and 2000s had a buzz cut. Now, there is a modern twist on that old military cut your child can try on. It still gives a clean look but adds a layer with the fade on the sides. If your child doesn't like to get ready in the mornings, this cut will save everyone time while still leaving him looking sharp.
The pompadour
The pompadour is such an adorable cut that dresses up any look when styled with a bit of product. Throw in a fade on the sides and back, and you have the ultimate look. The classic sweep and slick back of the pompadour clean up any kiddo, but the added fade along the edges is a fresh take.
Faded comb over
Don't worry -- no one will look older than their years with this faded comb-over look. It's a cute take on the original comb over, with the fade blending into the section that gets combed over. Add a shaved line at the part where you have the longer hair on top to the side to bring the homage home.
Faded side part
Close to the fade comb over, the faded side part works so well with kids who have a natural part on the side. It gives the natural lay of the hair a style that can be done in seconds, which is great for kids and parents, and plays off how the hair goes normally. Keep the top as short or long as you want and do a higher fade on the side of the part to allow for quick styling.

Baby playing on tummy and reaching for a toy

It's not uncommon for babies to dislike tummy time, especially for those just being introduced to this new position. It can be a bit stressful for parents when their baby starts to cry or squeal the minute they're placed on their stomach, but it doesn't have to be. There are many ways to get a baby to like tummy time; it's just a matter of finding the right strategy for your unique child.

Tummy time is when you place the baby on their belly so they can work their core and neck muscles to get them ready for new activities like rolling over, sitting up, and crawling. Studies have shown that when tummy time isn't as encouraged, babies are likelier not to crawl. They've also shown that babies who spend more time on their tummies crawl sooner. The WHO recommends tummy time which has also been shown to improve gross motor skills and overall development and prevent flat head syndrome.

Crying is a way for babies to communicate. Babies cry for many reasons, but when a newborn won't stop crying, it can be extremely worrisome, especially for new parents.
