For the past 5 days Isaac has been a different baby after his feeds, as he has been throwing lots of it back up, and he's never been a sicky baby We thought it was something to do with constipation as he didn't go for nearly 30hrs, but when he did it was loose and not hard at all On the plus side he seems as alert and active as ever, but don't understand how he can be after throwing up so much feed when previously he'd keep it all down? He's also been taking longer to settle for his 'big' sleep in the evening too, when previously he'd go down within 30mins no bother. Anyone any advice?
