Re: I have NO IDEA how much ebm to send!
I think at 3.5 mo mine was taking about 4 oz or so. I'd make sure to send an extra bottle, so that if you underestimated, they won't be short on milk.
The biggest piece of advice I can give you is start stocking up on milk now! I made the mistake of only having about a 2 day supply of milk pumped, and ended up playing catch up. Setting an alarm clock for 3 am just so you can get up to pump so your baby will have enough at daycare the next day STINKS!
Good luck mama! And a big pat on the back for not quitting bf'ing to send baby to daycare!
