how much should a 8 month old baby eat at a feeding ? (formula)

My daughter is taking 4 ounces every 5-6 hours

my son at 8 months ate 4-6oz every 3-4 hrs

my almost 8 month old eats about 5 ounces every 4 to 6 hours sometime it's only 3 or 4 ounces if to much is going on around her she lol...she eats solids also and she doesn't have a bottle during the night

wow my daughter eats way to much then. she's only a month an she eats 4 oz every 2-3 hours lol

@melissafrattinger every baby is different...my baby was at 4 ounces at almost two months by 4 months she was up to 5...and has stayed at 5 now for 4 months...if she's not spitting up a lot (some is normal) and seems content it's not to much.

mines eating 8 ounces a feeding or baby food and 4 ounces
