OK so evie is now 2 weeks old and I have managed to breast feed her for her 1st week then I've expressed milk for her 2nd week but I'm finding it difficult to "socialise" around expressing and feeding, like going out for dinner and going out for the day etc and I'm really tired with late nights and early hours expressing too so I think I'm going to have to go to formula but not sure which one to have for her... what are you ladies using and why?
