Still expecting, new to BF, got a few questions...

BethAndBen

Ladies, I plan to breastfeeding my LO and have a few questions for more experienced mommies. So far all I have for breastfeeding is a hospital grade medals pump on reserve to rent from my hospital, a few washable breast pads and some of those soothes that go in the freezer. What else do i need and what is imperative to have at the hospital and during those first few weeks? What do you prefer to freeze milk in? I have seen trays, that look like ice cube trays with a lid, and am interested in those since it seems convenient. Has anyone used them or are the bags better? We are planning to use Tommee Tippee bottles unless LO has different plans. I will be going back to work past time, 4 hours a day, at 12 weeks. Any help, advice or product recommendations are greatly appreciated!! Thanks!
