DS is exactly 17 months old. He is a good night sleeper and will sleep usually 11 and a half to 12 hours at night. He is put down at 6.45 and wakes between 6.15 and 6.45, ocassionally 6. No problem with any of this.
He dropped to one nap at 14 months, and started having a solid 1.5 hour nap after lunch, sometimes but rarely 2 hours. This is from 12.30 or 1pm depending on when he wakes up.
In the last 3 weeks, he has been waking up from his nap between 1hr and 1.hr 20 minutes, and in the last 2 days 40 minutes only. Today I've popped in to check his nappy and given him a kiss and put him back down but I'm pretty sure he'll be shouting shortly and I'll have to get him out! He's not ratty when he wakes but is a nightmare by about 5 or 5.30pm. We are busy pretty much every morning, he walks a lot and today for example we've played at the beach and had a walk so he's not under exercised.
It's not teeth - he has had 16 teeth for a long while now and no signs of the 2 year molars yet.
He's not dropping this already is he?! DD dropped her nap by 2.3 but we are still a way from that - I was hoping to get to at least 2!
