My 5 week old used to feed happily for about 20-30 mins on one side. Have a burp and a quick rest and then go on the second side for about 15-20 mins.
She is now just going on one side for about 20-30 mins and then falls asleep and isnt interested in the second side.
Do I have anything to worry about? She's been doing this since we introduced infacol 3 days ago (coincidence?).
