Why is my 4-month-old baby not gaining weight?

Slow weight gain in a 4-month-old baby can result from several different causes. The most common ones are:

Feeding patterns: If breastfed, the milk supply may not be enough, or your baby may tire during nursing and not get enough. With formula switching, the right amount needs to be adjusted.

Natural slowdown in growth rate: Around 4 months, babies' weight gain speed naturally slows compared to the first few months. Gaining 100-150 grams per week is still considered normal.

Reflux or feeding problems: Frequent spitting up, discomfort after feeds, or physical issues like tongue-tie can prevent consumed milk from staying in the body.

Hidden illness or infection: Unnoticed ear infections, urinary tract infections, or other illnesses can reduce appetite.

Regardless, a clear picture requires looking at your baby's birth weight, weekly growth rate, and overall health together. If weight gain has slowed or stopped in the last 1-2 weeks, I'd strongly urge you to check with your pediatrician — timely action at this age is important.
