Hello Jyoti, I am currently using Dr. Brown bottle with level 3 nipple for my baby. She has slowly started accepting it after 10 days now. Make sure you feed the baby with the bottle when he is moderately hungry. Babies don't accept new things when they are very hungry. It might take a few days. Have patience and don't force feed.
