I'm sensitive to smells. If you can't stand being in there I wouldn't let my child sleep in their either. I too would look for something that could absorb the smell. Kitty litter? Also, maybe you could wipe down the walls. I realize the paint is volatilizing, but maybe the smell is more intense on the surface. Check to see if a vinegar/water solution would be safe for the paint. I think it would be, and I just researched how to get a burn microwave popcorn smell off walls (sis-in-law), and that was a common suggestion.
