DD is 9.5 months, and I've only recently got her into a good nap rountine of going off on her own and having at least an hour morning and afternoon - she used to be dreadful. But on Sunday she discovered she could stand up in her cot, now she won't go off! Already been up twice in last 15 mins, keep laying her back down and she keeps getting back up again, despite being really tired. She uses a sleeping bag at night, but that doesn't stop her, she's been waking up in the night and when I go in she's standing there waiting for me!! HELP!
