My almost 7-mo has been co-sleeping well since birth. She used to sleep 5-6 hours straight, but now she wakes up several times a night to nurse. I figure it's because she's now active and needs the nourishment. Her usual routine the past few weeks is to wake up and nurse and then roll over to daddy and cuddle. A few nights ago, she started crawling around the bed a lot. And it seems that she is still asleep when she is crawling around. Could she be sleep-crawling? Has anybody else had this? What do you do about it? We're afraid she might crawl off the end of the bed or something. Just wondering what's up and what can we do?
