HI A.
Itis possible to get the wallpaper off and paint all in the same day?
Just ask her if she is using latex or enamil paint- latex has slight odors and will fade within 30 minutes or so- as long as the windows are open and there is plenty of fresh air- enamel paint around little ones is a big no no.
just take plenty of toys to keep him occupied or possibly put him in a pac andplay near an open window or door- should not e a problem.
good luck and blessings
