Question
Daughter, 5 months old: My daughter’s breasts have been getting larger recently. They were normal before. What’s going on, and I’m worried.
Answer
Considering the possibility of a physiological mini-puberty, I suggest you check your baby’s endocrine system first. If your baby is breastfed, it’s recommended to pay attention to a light and easily digestible diet for yourself. If formula-fed, consider whether there might be an issue with the formula, and consider switching if necessary. Follow-up Question: My baby is breastfed. If it’s physiological, how long will it take to go down? What should I be observing on a regular basis? Answer: It’s recommended to observe for two months; this condition typically resolves as the baby grows older, and it’s also important to ensure the baby doesn’t become overweight.
