Does your child wake up during the night?

No, my 11 week old does not.

Neither does my 3 year old, just once in a while she will crawl into the bed with us, and we don't even realize she did until morning, haha.

My 11 month old wakes up at least once. My 2 year old usually doesn't. My 4 year old sometimes does. My 5 year old doesn't.

she is 21 months and lately she has been waking for a change and a little cuddle time.  My 4 yr old doesnt although we want her to wake to go potty.

yes for a feeding.

not usually, he only wakes up if he's had a bad dream.

She gets up at least once or twice a week at night for a feeding. We just started this a two weeks ago. Before she was up 2-4 times a night for some time and she is 15 months old.

Lately, yes.  It's both a good and a bad thing she gets 3 and 4 teeth at a time.  Oh sure, it's miserable now, but once theyr'e through, she'll be done for a good long time.
