Can anyone help! My DS is 7 weeks old and was B/F until 2 weeks ago without problems. My milk supply was disrupted and hasnt come back properly since so have had to supplement with formula. He needs topping up after breast feeds in the afternoon and evening. He took to the bottle immediately but became ill as a result of the type of formula. Have since swapped at Health Vis recommendation. He stopped taking bottle yesterday completely but screamed all evening as was starving. Any ideas - as am pulling my hair out?
