my eldest didn't sleep more than 2 hours at a time until she was 2 years old. 2. she didn't nap for more than 20 minutes until she was 18 months old.at 2 I managed to get 90 mins napping if I drove around for an hour first, I gave up at 28 months. She was never grumpy, just me :-) Now, she sleeps from 8 till 6.30 ish every night yahoo.

Have to say though that we later discovered allergies had a big part to play so it might be wroth checking that out...

DS1 who is way further ahead on all milestones to DD has always slept well, but he gave up morning naps at 10 months. Now he does 7 till 5/6am and then 12 - 1.30 lick clockword. After DD this is terribly exciting for me!
