my 4months baby reduced taking of milk,he is drinking for 2minutes only what should I do, he is licking all the things what ever he got how can I reduced this

A. hello as baby grows it will be able to suck the milk faster and also you should try to feed your baby in a silent place with no distraction and also if the baby is not a able to take well then you can even try to express your milk and feed the same in the bottle
