How often and for how long do your babes sleep during the day
DS is 6 months old and I feel like he gets tired very quickly. He sleeps roughly 13 hours at night (asleep by 6:30 latest and is up between 7-8AM). After. He's woken up, had his bottle and a bit of play he's usually ready for a nap about 1-1/2 hours after waking up, and will then sleep anywhere from 2-4 hours (yesterday was 9-1!).
He very rarely can go longer than 2 hours before being very cranky. He's fairly active; rolls constantly, commando crawls, tries to actually crawl, etc.
Do I just have a baby who likes his sleep? He has baby friend who are 2 months younger than him and are awake for much longer periods of time. I worry that with all the sleep he's not eating enough (formula).
