Missy, sorry to hear you guys are still having sleeping issues. My DD started this, but I think she was much older when she did? Possibly somewhere around 4 or 5? It could've been when she was adjusting to something new, like pre school?
I think all we did was keep putting her back to bed, and it went on for months and months too.

Do you think that maybe something like a night light might entice him to stay in bed? Or a special new pillow or doona cover that he can pick out himself, might entice him to stay in his room? Maybe a new cuddly toy or something? It's all I can think of, sorry.

Hope you can get some sleep soon. lots of hugs

Nic
