Beauty editor Barbie Ritzman of Barbie’s Beauty Bits approaches topics like this from a real-world, everyday perspective. I always think it helps when information like this is broken down simply, especially when you are trying to figure things out in the moment.
Why Is My Baby So Fussy and Crying?
There are many reasons a baby can be fussy, and for parents, especially first-time parents, it can be worrying to think something is wrong. But the reality is the world is brand new, they’re learning as they go, and crying is the main form of communication to express everything.It’s easy to feel like you’re doing something wrong when your baby won’t settle.
For the most part, if your baby is fussy, it’s rarely random or for no reason at all, especially in the first few weeks.
But knowing the triggers, knowing what to check and look for, can be extremely helpful in calming your baby faster. I think this is where most of the stress comes from, not knowing what to check first.The hardest part is not knowing what your baby needs in that moment.
Let’s take a look.
Your Baby Could Be Hungry
If your baby is fussy and crying, hunger is often one of the first things to check. Babies have a small stomach, so they need to be fed regularly, and hunger can quickly make them uncomfortable.
Babies usually go about 3 hours between feeds, but this isn’t a hard-and-fast rule, especially as they grow and develop.
Watch for signs like lip smacking, rooting, sucking motions, or fussing at the bottle or breast. They might also bring their hands to their mouth or make sucking sounds during or after feeding.
All of these signals can indicate they are still hungry. Offering a feed, even if they just ate, can sometimes make all the difference. I’ve seen that sometimes it’s the smallest extra feed that helps them calm down.
Tracking feeds can also help you spot patterns and better understand their hunger cues.
Could Be an Illness or Fever
If your baby is fussy and crying more than usual, illness could be a possible cause. Checking their temperature can help rule out a fever.
A fever often comes with other signs like tiredness, more intense crying, congestion, or rashes. Your baby might sleep more or be harder to comfort.
If they have a fever over 100.4°F and are under 3 months old, you should seek medical care right away.
If you’re unsure, it’s always better to check with your pediatrician. I personally believe it’s better to be cautious than wait it out.
Your Baby May Not Be Getting Enough Sleep
If your baby is fussy and struggling to settle, being overly tired is a very common reason. Newborns can sleep up to 17 hours a day, but missing sleep can quickly lead to irritability.
Look for signs like yawning, eye rubbing, zoning out, or sudden bursts of energy. These can all signal that your baby is overtired. Understanding whether your baby is overtired or undertired helps you address their sleep patterns more effectively. Tracking sleep patterns can help you understand when your baby is likely to get fussy. Small changes like dimming the lights, swaddling, or using white noise can help them relax.
I’ve noticed that sometimes the environment makes a bigger difference than expected.It’s Teething TimeIf your baby is fussy and chewing on hands or toys more than usual, teething could be the cause. It can begin before you even see a tooth.
Babies start teething at different ages; some get their first tooth within months, others are much older and can be closer to 12 months old before their first tooth appears. However, teething can start long before a tooth breaks through the gums.
Teething can cause irritability, sore gums, red cheeks, and changes in feeding.
Cold teething rings, gentle gum massage, and baby-safe remedies can help soothe discomfort.Your Baby Could Have Gas or ColicIf your baby is crying intensely or seems uncomfortable, gas or colic could be contributing to the fussiness.
You might notice them pulling their legs up, arching their back, or crying more sharply.
Sometimes the fix is simple, like gentle tummy massage or holding them upright after feeding. I think this is one of the most overlooked causes until you see how quickly relief can help.
Slowing feeds down, burping more frequently, and keeping your baby upright for longer after feeding can also help prevent discomfort before it starts.Diaper DiscomfortIf your baby is fussy for no clear reason, diaper discomfort is another possibility to check.
This isn’t so much about how frequently you’re changing the diapers as such, but is the diaper absorbent enough or the right fit? Because if it’s not as absorbent as it needs to be, then this might be irritating their skin as they empty the bladder or bowels as needed.
If the fit is wrong, this could also be causing irritation on their body, making it uncomfortable for them to wear.
Always check the absorbency by feeling the weight of the diaper and checking your baby’s skin when you change them. Look for rashes or red marks around where the edge of the diaper sits. This can be a sign that you may need to change sizes or try a different brand.Figuring Out the Cause
Understanding why your baby is fussy can help you feel more confident and less overwhelmed. This is especially true for first-time parents who are still learning patterns and cues.
That said, there will still be moments where nothing seems to work.In the middle of trying to figure everything out, it’s easy to lose sight of yourself too, but taking small steps to feel confident and comfortable in your own skin can help bring that back.
Schedule vs Following Cues
Some parents follow strict schedules, while others respond to cues in real time.
Schedules can create structure, but they don’t always match your baby’s needs perfectly. A cue-based approach is more flexible but can take time to learn.
Most parents naturally end up using a mix of both.
Final Thoughts
At the end of the day, a fussy baby is not random, even if it feels that way. There is usually a reason, and over time, those patterns become easier to recognize.
I think this is where confidence really starts to build. Not because everything suddenly becomes easy, but because you begin to understand what your baby is trying to communicate.
Some days will still feel unpredictable, and not every solution will work every time. That is completely normal. The more you observe, adjust, and respond, the more you will find what works best for you and your baby.If you’re navigating those early weeks with a newborn, taking care of yourself matters just as much.
