He's nearly 2 weeks, and not putting weight on at a good enough rate so I have been advised to top up every feed if he needs it, not just once a day. I want to know how much formula he would be getting if he was ex FF, so I can judge roughly how many mls he is getting from the breast? I mean if he drinks 50mls of FM after a BF, roughly how much BM has he drunk?
Thanks
