How often and how long do you have to feed a bottle baby. Mind born Monday evening is now eating an 6-1/2 oz baby bottle full. I feed him in the morning about 7:30am, the wife feeds around 12 noon, I feed him again about 4:30pm and at 9;30pm. Mom still don’t try to feed him. Just wondering how long it takes for them to start eating alfalfa pellets. I think about weeks if mama is involved , but here it might take longer?
