I have a similar question to the "I am not a Juice Box" mummy. My 4 month old baby boy doesn't necessarily play, but his new habit is to push HARD with his little fists against my breast and at the same time pull away while he sucks. Like I am a balloon or something! He will usually eventually settle down and nurse contentedly, but I'm not sure what to do while he's nursing AGGRESSIVELY. It is a bit painful after a while. I have tried relocating his fist, and also gently pulling him towards me to lessen the yanking away. Any other tips? This is my first experience nursing as my other children are all adopted so any help is greatly appreciated. I LOVE being able to feed my baby!!
