is 3 oz enough at 8 weeks?

DH gives DD a 4 oz bottle every night but she rarely takes the whole thing. She seems content though at the end of the feeding and goes 3 hrs between feedings or longer at night and does just fine. Should we be concerned that she's not getting enough though?

PS...It's pumped breastmilk and I BF the rest of the day. She has been eating 10 min on one side and then 5-10 on the other pretty consistently at each feeding.

I don't think you should be concerned....my DS was the same way at 8 weeks, I pretty much EBF, but at that time on a day DH would give DS a bottle, he usually took 3oz and was perfectly content. If she seems content and is gaining well with plenty of wet diapers I think you are doing fine. I was also a little worried around that time because DS was nursing for less time, but I think he just was getting more efficient at nursing.

As long as your baby is happy, sleeping good and gaining wieght... your good.
