What to do if my 3-month-old baby refuses formula milk and bottle but is breastfeeding well?

Your baby’s breastfeeding well and not exhibiting any concerning symptoms like reduced urine output or vomiting, which is reassuring. It sounds like your primary concern is the refusal of formula and bottle feeding. It’s not uncommon for breastfed babies to refuse bottle feeding or formula since they are used to breastfeeding. Since your baby is thriving on breast milk, it might be a matter of preference or familiarity. If you need to introduce the bottle or formula, try offering the bottle when your baby is calm, perhaps midway between feedings so they aren’t too hungry or tired. Experimenting with different temperatures of the milk might also help, as some babies prefer milk warmer or cooler than room temperature. You could also continue to try different bottle nipples, as some babies are picky about the flow rate or texture. Enlist the help of another family member to offer the bottle, as the baby may associate you primarily with breastfeeding and resist bottle feeding from you. Offering the bottle in a different position or environment can sometimes make a difference. Since your baby urinates normally and isn’t vomiting, it suggests adequate hydration and nutrition. However, if the need to supplement with formula increases or your baby shows signs of not getting enough nutrition, consult your pediatrician. They might check growth parameters to ensure your baby is gaining weight appropriately. While introducing a bottle or formula can sometimes be challenging, ensuring your baby’s growth and health is key, so that should be your main focus.
