Hallo! Honestly, I'd wait until after you deliver first, most of us mummies here actually did that because you really won't know your supply until baby comes and you start nursing. If you end up having plenty of milk and need to express (maybe for engorgement or if you're going back to work), then you can decide between manual pump or electric depending on your lifestyle, I have a few mum friends who swear by manual pumps for occasional use, while others preferred electric for daily expressing. No rush to buy before, you'll have a clearer picture once baby is here and you've settled into breastfeeding!
