When I BF DD, I pumped into bottles, gave it to her daycare provider and she put it into bottles for her. DS2 is being watched by my ILs 3 days a week now, so I'm making the bottles. I'm making him three 3 oz bottles to start and he's doing fine on them. I'm pumping 21-25 oz a day, so the leftover is getting frozen. I have so much frozen milk now, at least in comparison to the none I had leftover last time.
I'm just sick thinking about all of the milk that was probably tossed for DD! I pumped for 11 mos and supplemented with formula from 9 mos on at daycare. Probably could have avoided all of that if I'd made the bottles myself. =(
