Our DD was doing the same exact thing right after the 2-1 switch! But she would be awake for 30 minute to 1.5 hours!! And not crying either, just AWAKE! Playing, talking, rolling around. Sometimes she would end up crying which was the worst because she would go down at 7:30 and we would be downstairs trying to relax, but you could hear her awake up there and then at 9:00 she would finally get bored and start crying and I'd have to go and do WI/WO or GW for a little while. I thought at first she was OT, I mean we DID cut out a nap. So we tried putting her to bed a little earlier, that made it worse. VERY surprisingly it only got better when DH suggested putting her down for bedtime LATER. I thought he was nuts, but agreed to try it. Sure enough, we held her out till 8:00 and she went to sleep much quicker and after 2 days was going right to sleep. We did that for about a week or so and then gradually moved her back to a 7:30 bedtime, and she has been doing fine since. I know this is not the norm!! But in case the earlier bedtime makes it worse for you too, at least you know some babies are wacky like mine! LOL!!
