Can you pump and feed them Breast milk from a bottle instead it using nips.

Just do a lot of research if you're planning to exclusively pump. It's much harder than breastfeeding. You have to pump every 2-3 hours (that includes at night time). While that's the same with breastfeeding you're attached to your machine, have to clean the parts, and still feed the baby and clean the bottle. It's a lot!

Okay. I'll look into those. Thank you! ❤️

Absolutely. Tommee tippee bottles are good. Also I can't remember if it's Nuk or munchkin brand but there are latch bottles that are very similar to a nipple that worked great for my sister

What's the best bottles to use?

sure can!! lots of mommies who have to go back to work use that route!

I've just never heard of anyone doing it that way before.

Absolutely. Whatever's comfortable for you!
