We adopted a cat a couple weeks ago and he was doing really well leaving my daughter's crib alone. We lowered her crib to the lowest setting 2 nights ago and the last two nights he has jumped in her crib while she was sleeping and woke her up. Our room doesn't have a door annoyingly, so until we can find a door to fit our room and shut him out, does anyone have any tips to teach him to stay away from her crib? I can't figure out why all of the sudden he's interested in her crib. Literally the only thing that's changed is we lowered the mattress.
