Hello I have been combi feeding for a week and half now after a rough start of solely breastfeeding and my baby losing a lot of weight, I was recommended to hire a hospital grade pump to increase my milk supply which I have but it isn't practical for night time as I'm finding it really hard to get up between 3-5am to express when my milk is at its highest, can anyone recommend a good portable breast pump to help me increase milk supply and that I can use during the night?? T.i.a
