So, I go back to work on Monday. Today we were just around the house so I did bottles when I would normally be at work. Our day went like this:

6 am ( why when we had nowhere to go!) nurse
Nap 2.5 hours
9:20 am 4 oz bottle, drank 2 oz before she stopped. I think she could have had more, but we were at church and I was worried she was going to drink too much, too quickly and then spit it up. Plus, she stopped acting interested in eating then.
Nap
11:45 am 4 oz bottle, drank 3.5 oz
Nap 2.5 hours
3:00 pm 5 oz bottle (thought I'd see if she actually took that much), drank only 3 oz.
45 minute nap
5:15 nursed both sides.

What do you think I should try tomorrow? I was worried about giving her too much or too little. She had a bottle with my mom on Sunday and she ended up drinking too much too quickly and threw it all back up.

She is 3 months old. She shows signs that she is hungry, fists in mouth, etc., but I also think that's just her age. I'm thinking of sending 3 4 oz. bottles. What you think or suggest?
