My LO is almost 10 weeks old, I've been back to work since he was 6 weeks. I pump at work and send that milk to daycare, she has a can of formula for emergencies only, basically I was really worried at the beginning I wasn't going to send enough milk. She's never used the formula though.
During the week daddy picks up the boys from daycare and I always leave him a bag of milk for the feeding before I get home. Yesterday I noticed there was still some in the bottle so I asked how much he ate, my husband told me it was formula. He said he understands that I want to continue to nurse and he doesn't want to take that from me, but he thinks that my milk isn't filling him up. Yesterday he didn't sleep but 1 1/2 hrs at daycare and the night prior he had been up nursing every 2 hours. I normally get a good 5 hr stretch out of him so I just chalked it up to a growth spurt or something. He cosleeps so it's not like it was horrible being up every 2 hours, just different. My husband said if we give him 1 formula a bottle at night that will help him sleep (not sure why it bothers him since he doesn't wake up with him). I'm extremely frustrated because with my last son I was only able to breastfeed to 4 months. Braeden is porking right up, I have no problem with nursing on demand, that's how I've been doing it since birth. But now I have my daycare provider almost frustrated he wants to eat every 2 hours and telling my husband that it's possible he just needs more, like her son did.
