my baby is 3 month old. she's sucking her lower lip. whether I should stop her or not?

A. It's normal for a 3-month-old baby to suck on their lower lip as part of exploring their body and developing self-soothing behaviors. This phase is typically harmless and part of their growth. You don’t need to stop her unless: 1. She is causing irritation or redness: In that case, gently distract her with a pacifier, teether, or toys. 2. It interferes with feeding: If sucking her lip reduces her feeding interest, ensure she gets adequate nutrition by gently redirecting her to feed. Monitor her for any skin issues around the lips and consult a pediatrician if you notice persistent problems like sores or feeding difficulties. Otherwise, let her enjoy this normal developmental milestone!
