Not sure if 6 hours is considered sleeping through but after over a week of worst sleep ever with 5 week old DD (cluster feeding so up every hour), last night she slept 6 hours straight! 6 hours without a feed and she didn't even go mad for one when I woke her (she fed but wasn't like feed me NOW!) is this normal for DC to sleep 6 hours straight at 5 weeks? Maybe she is ill!? (Ps I know I should just enjoy it as I'm hanging with lack of sleep but worried)
