How often should I be feeding my 5 month old (she is almost 6 months)?

I think it depends on the baby and how much she drinks. My son was drinking 6oz every 3 hours and like 3 weeks ago changed to 7oz every 4 hours.

how much of babyfood should she be eating?

It depends on the baby. Most are eating every 2 to 3 hours

Baby food isn't recommended until 6 months and above and it's really as much as they can eat. I would start with a half jar

my baby girl is 5 in a half months old... she eats baby food all the time.. I feed her all she wants she will let you know when she's done.. @supercrunchymommy . just not a lot of bananas.

why not a lot of bananas?

Bananas are full of sugar
