My baby is 3 weeks old and feeds every 2 to 2 and a half hours and has between 90ml and 120 ml each feed. This is really tiring during the night especially as my OH works so i end up doing the night feeds on my own most nights. my health visitor said she is probably feeding too much but you can hear her tummy groan when she feeds so she must be hungry. She weighed 8.9lb last time she was weighed and that was 6 days ago so she'll weigh more now. I'm considering trying hungry baby milk, she currently has a mix of breast milk and sma gold, but i don't know if its good for babies. My LO cries when she poos and I'm concerned it may make it harder for her to go. Has anyone had any experience of hungry baby milk. Does it work. Is it good for babies. And could it cause constipation. I'd really appreciate any advice x
