Hi -my baby is 13wks, I have been bf but she started to feed every 1.5hrs as she was so hungry and she was never happy. I have now started to 'top her up' with formula after every feed and she seems so much happier but I feel so dreadful about it as I desperately want to carry on BF and give her the best start I can. I have tried everything to boost my milk supply - expressing every hour, Fenugreek etc but nothing seems to work. When I express I can only get about 2oz and she needs about 5oz so I know I don't have enough for her. Also I started my period at around the time my milk supply dropped is this linked ?
