Oh I'm SO glad we read this thread!
DS has been a good sleeper since 8 weeks old, with occasional interruptions for teething, sickness etc. (Thank you Beatrice Hollyer!)
He's now nearly 9 months, active, alert, mobile, busy, and flinging himself around the place collecting bruises.
Bedtimes have gone from 20 minute bath, dress and feed, to two hour bath, dress and feed, put down, pick up, put down, leave the room, shake the cot, yell, look out the window, get leg trapped in bars, yell again, stand up, scream, pick up, put down, stand up, scream, scream, shake, scream......
The standing IS compulsive. He was even trying it when asleep. He only got to sleep cos he dropped off in my arms, then I put him in the cot, at which he woke up, but I put him on his belly and HELD his pelvis flat with my hand so he couldn't stand.
If we want him to nap during the day, one of us gets him into our bed and restrains him until he falls asleep (we know when he has woken up again - we hear the "THUMP" as he falls off the bed).
I'm so glad it's only a phase. We thought it was. We're going to move his nap forward (he's dropped a nap) to about 12-2, and then see how we get on.
Still, it's all worth it to see his smile in the morning...
