How many ounces ?

Le

I’m returning to work when baby is 12 weeks old. I’m wanting to pump and freeze some milk before hand just in case my supply decreases or daycare over feeds when I return to work.

My question is how many ounces should I be freezing together? 3 or 4 ounces? Some of each? I’m so clueless.

What do you send with your baby? She’ll be at daycare for a little over 9 hours a day.

Also when should I introduce a bottle?
