DD did and does this still.

i have put it in the 'completely normal' basket...

at times i even find her fully asleep, complaining and STANDING UP.

all it takes from our side is usually a rearrange in the bed (so for example, i pull her back to the middle of the bed...cause she has crawled all whacko over the place) and put her sheets back up.

for the crying thing, i do the same, and sometimes i gently say her name and put a soft but firm pressure on her back/belly and leave.

for the most part we now ignore it and find that once that dream cycle has ended she is back to the land of zzzzzzzzzz.

HTH babe
