My 9 week old boy for the past week is sick a lot from around 4pm onwards. I initially thought he was feeding too much during the day but I have watched closely the amount of food he has had today and I don't think he has been eating too much (I prepare a 6oz bottle demand feed but he often doesn't finish it in the 2 hours it's safe to eat). This is a stupid question but is it normal for babies to be 'sicky' towards the end of the day or is this something I should be visiting the doctor about?x
