So my mom got a sleep wedge for the crib today just don't know if it is safe. Could I call who is going to be the…

Yup you put it under the mattress...or maybe under the sheet? (if I'm thinking of the same thing), and it helps baby not get congested. I had one for my girls

This one goes under the sheet

Call and check if you're worried but I loved mine. My girls were very snotty babies and it helped a lot

i used one with my kids and it was wonderful.

It's just I'm a ftm and trying to figure out what's a danger and what isn't and what is one of those lets scare new parents so much they don't wanna put their baby down anywhere things is impossible
