Why is my 4-month-old baby fussy?

The most common reasons for fussiness in 4-month-olds are:
- 4-month sleep regression: The baby's sleep cycle starts to resemble an adult's; frequent wakings and crying occur.
- Teething signs: Some babies show gum swelling, heavy drooling, and putting fingers/objects in their mouth.
- Growth spurt: Rapid motor and cognitive development makes babies more demanding and fussy.
- Gas or reflux: Especially after feeding — pulling legs toward belly, writhing, back-arching if you lay them down can signal discomfort.
- Overstimulation or tiredness: Babies who get too much input during the day or miss their sleep window cry in protest.
- Infection: If fever, congestion, ear-tugging, or other symptoms are present, see your pediatrician.
Current pediatric thinking is that most 4-month fussiness is a normal developmental phase. Without fever, vomiting, diarrhea, rash, or 8+ hours of dry diapers, there's usually no cause for alarm. Regular feeding/sleep/diaper tracking is sufficient. If fussiness lasts more than 1-2 weeks or affects your baby's weight gain, check with your pediatrician.
