What it says on the tin - my DD is 9.5 weeks and only sleeping around 8-12 hours a day (5hr chunks at night, not great but not complaining!) but everything I've read said she should be getting 15-17 hours at this point... she'll nap for longer during the day if i keep her on me, or pram/car, but she won't settle in her basket or cot in the day and wakes up if i put her down. Should i be trying to get her to sleep longer or accept she's just a wakeful little thing?
