For my mommy’s that bottle feed or did

About how many ounces of milk did you get your baby at 3 weeks && how often? My daughter will be a month old next week and i give her 2ozs every 2-3 hours. But sometimes she stretches her sleep and she’ll sleep past her 2-3 feeding time which is too 4/5 hours. I feel like I need to up her ounces to maybe a half or 3ozs. Doctor said it wouldn’t hurt considering she only weighs 6.12ozs. I just don’t wanna overfeed her
