advised to give formula

[VictoriaH]

My baby is now a month old (first baby). She weighed 6.7 at birth and now only 7.3, I've been told this is a very small increase and have to supplement breast feeding with formula. Am using Aptimal, started yesterday and she seems slightly more sick since. Is formula ok and has anyone else been advised to top up like this? my boyfriend is totally against me using formula and being very unsupportive but she needs to put on weight and obviously not getting enough from breastfeeding alone, he seems to think she should not need formula and that I should be capable of providing all she needs and am usless for not doing so. What can I do?

Tiktok will give a more expert view, but for a baby only a few weeks old feeding every 3 hours during the day is unlikely to be enough. IMO you should be aiming for at least every 2 hours, and potentially more often at the moment as your DD has been losing weight and you need to build up supply after weeks of less frequent feeds.

I think, broadly, what you've started doing now is the right thing -- feed more often and on both sides (or even, as Tiktok says, on three sides by swapping back to the first side again). You need to "empty" (not that they are ever really empty, but YKWIM) both breasts as often as possible to build up your supply, and it is going to be tough on you for the first few days. Have you had your latch checked at all?
