POOJA KOTHARIMom of a 8 yr 5 m old boy8 months agoA. It's quite common for a 4-month-old baby to suck on their fingers or thumb, especially while sleeping. This behavior is a natural self-soothing mechanism and can help them feel secure and calm. At this age, babies often explore their hands as a way of comforting themselves. There’s no need to worry as it's typically a harmless habit at this stage. However, if you are concerned about the thumb-sucking becoming a long-term habit, you can try gently offering a pacifier as an alternative to help with self-soothing. Avoid pressuring your baby to stop, as thumb-sucking is often something that naturally reduces with time as babies grow and find other ways to comfort themselves. If the habit continues or if you have concerns about it later, consulting your pediatrician might help to ensure everything is on track with your baby's development.
