Why does a 4-month-old baby put their hand in their mouth? My mother-in-law says one thing, I read something else.

For a 4-month-old putting their hand in their mouth is completely normal and actually a healthy developmental stage. At this age, babies start exploring the world through their mouths — hand-mouth coordination develops and often they do this to relieve pressure on their gums (teething can start at 4 months). It's also one of their self-soothing methods.
Your mother-in-law might interpret this as 'the baby is hungry' or 'the baby is bored,' which is typical of older generations. But current pediatric understanding says this is often exploration and a sensory need. As long as your baby's hand-to-mouth action isn't accompanied by fussiness, fever, or weight loss, there's no need to worry. You can offer a teething ring or clean cloth, but don't try to stop your baby from putting their hands in their mouth — it's a natural part of their development.
