DS is 4.5 months, excl. BF, gaining weight perfectly. We had some projectile pukes when he was very little but they stopped after I cut out dairy. This week he has done a huge, exorcist style puke once a day after a feed. He's not upset by them & is now chattering to himself in his cot as I sluice regurgitated BM off me and the sofa. Still have wet & dirty nappies and he's sleeping fine. Doctor says it could just be a GI bug and provided he's not bringing up every feed just to keep an eye on it. I just read that another cause could be overfeeding - anyone have any experience with this?? I do sense that he's starting to space out his feeds a bit but I'm still offering every 3 hours out of concern that if he goes longer bwn feeds he won't get enough to give him (and us) a long stretch of overnight sleep. Does anyone have any experience with this type of thing? Thank you!
