i just take as long as my dd needs and explain to ds when i get back out there that she was taking a while longer then normal and thanks for playing/reading quietly. i have to do this for every sleep as i have no one here to help at any sleep time.

i guess make sure its a long movie you have put on....
but also i pop in and out some days to check and she is getting used to going to sleep with out me there even though i might come back in (iykwim)
