At the risk of being horrible, many many 3-month old babies are very fussy at the boob. She's taking EBM OK - which is great for while you are at Uni. Why not continue to breastfeed her when you are around? It will mean less washing up for you and make maintaining a milk supply easier. And even if in a few months she's down to one or two breastmilk feeds a day that's still beneficial for you both. Surely a midwifery course has to be sympathetic to an expressing Mum?
