DD has done this since she was about 5 months old. And it is almost every night. She'll wake about 9:30-10pm and not go back to bed until 1am. Not fun when I have to get up at 5:30am. I wish she would just lie down next to me, even if she was to chat or clap her hands. But no, she has to sit up, stand up (leaning on me) and crawl around the bed and over me even if it means she's going to go headfirst off the bed. She cries if I put her in her cot.

I'd like to be able to have a room with just a mattress on the floor so that I could lie down and not worry about her hurting herself if I fall asleep, but we just don't have the space (DH is a horder and we have too much crap). I'm hoping that it will settle down when she's able to walk on her own. She did settle down briefly once she learnt to crawl, but she went from crawling to standing very quickly. But it is exhausting in the meantime.
