Re: !Need Advice ASAP! DD crawling out of crib. What do I do?
Is her room dark? I know if our room is dark our baby is not so into getting up to play in the middle of the night. If it was me, I'd take off the rail of the crib or at least lower it and put a soft landing so if she does fall out she doesn't get hurt. Or just turn it in to a toddler bed like you said and baby proof the room really well.
Personally, I'd also bring her into my room so I could keep tabs on her, but that's not an option for all families. I think I'd not spank because 18 months is pretty young and she's most likely doing it out of curiosity and not direct disobedience, IYKWIM?
Toughie. Hope you find something that works!
