Hi all, we breastfeed out baby but also give him a formula when my wife isn't producing enough or he's really hungry with the aim of making him sleep longer throughout the night. We've figure out that formula is the thing that makes him annoyed and not sleep which obviously makes it difficult for us. We want to be able to give formula sometimes but unsure what the problem might be. We've tried 4 different ones and none help, same result. Fyi we're not slow it's just that he had an operation on his stomach at 2 weeks so things have been a little difficult at times.
Thank you
Steve
