Wait till 8 weeks to start pumping? Go with different pump?

Beth.1212

The breast pump that I want (Ameda Purely Yours Ultra) is on back order at the DME that my insurance will cover. It looks like I have two options:

1. Wait a few weeks to get my breast pump - at that point, LO will be about 8 weeks old

2. Go with the Ameda Purely Yours, which they have in stock

Would it be problematic to wait to start pumping until 8 weeks, do you
think? Would you recommend waiting for the pump that I'd prefer or going with the more basic version?
