I follow a group on Facebook of babies born during the same month as ds2, and a few mums have had problems with babies dropping centiles along with hospital admissions, formula top ups etc. Despite all this they seem adamant they want to continue breastfeeding. I know bf is optimum when it works, but surely sometimes you need to admit it's just not working? Is it really that rewarding to the mum to keep trying through all the issues? In a few years will it even matter?
