My daughter is 5 weeks old and my supply has been so bad. We have pretty much been supplementing since birth because she lost so much weight. The midwives have said it is a combination of me not having enough milk (I will express for 2 hours and have 10 mls) and her not sucking properly. We have tried Nan gold, karicare aptimal gold and the Aldi one. All of them have made her really constipated. She will only poo maybe once every 3/4 days and when she does she screams and they are like marbles. Can anyone please tell me if they have any advice on what to do? It breaks my heart to see her so upset.
