Just wondering, how often does your 8 month old feed? Breastfeed that is! My son is now 6 months, he it pretty much still fully breastfed. he has about 2 or 3 naps a day and falls asleep on the boob each time and doesn't normally feed inbetween. I need to know because I was wondering how long I could go out for when he's about 8 months old
