Safety rails for beds for babies that go sleep check on Amazon and they’re made out of mesh
My baby does this too !!! She has her own side of the bed now bc she hatesss her crib and there are no blankets and pillows no where near. Every night she’s rolling on her belly it’s as if she’s more comfortable that way
When I transitioned my son from my bed to his crib I took one side of his crib off and put it against my bed so it's kind of like he's in my bed but he's not and when some time passes I'll put the side back on
do you sleep alone w baby and you in bed? is there enough space to put baby a little further from you with absolutely no blankets or pillows, so if he rolls over, it’s no big deal? is your bed firm enough for that? my little has recently started rolling all over at night to. she starts on her back, rolls to belly, back to back, to her side and usually ends up staying on her back half the night.
