My DS is 6 weeks old and feeds with mam bottles SMA comfort milk. But the older he gets the more he feeds, its starting to get me down a bit. He will have 4 floz and still be hungry and I’ll needs to fill his bottle again, and he’ll have a little bit more then he gets so full he spits up. This is every hour to 2 hours all day and all night. He’s started to guzzle his food he’s so hungry. I asked the HV if I should give hungry baby formula she said it’s not really for young babies and may cause constipation. I don’t want to make him ill but being hungry isn’t nice for him either. Can anyone suggest what I could do for him? Tia
