My little girl is 6 weeks old today. She’s an absolute dream and I’m probably a over worrier. She was born 7lb 1oz and at 5 days old was 7lb 8oz, 7lb 14oz at 13 days old, 5 weeks old she was 9lb 14oz. So she’s gained and never lost. She’s overall a good feeder. But I’ve noticed over the last week she is getting slow with her bottle. I don’t know if I’m just misreading her hunger. But for example through the night she will have 2oz of her 4oz bottle and go to sleep, wake up 3/4 hours later and do the same, sometimes take more. And she keeps doing that throughout the day, takes ages to feed her and it’s worrying me/stressful because no sooner she’s fed it’s time for the next feed and I just feel like my day is constantly feeding her as she’s so slow. She’s now starting to slightly spit up, sometimes vomit. She’s also not going for a poo everyday. Sometimes it’s every other day. Has anyone had this issue? And is something suddenly causing it?
