Getting crib set up safe for 7 mo old ?

i have almost always given my son a blanket in his crib, what i have done though, is given him a small one, thats just big enough to cover him up, its a knit one so it has holes so that even if he does get caught in it he can still breathe just fine, he m ostly likes to hug it and snuggle it more than using it to keep warm so this works for us,at 7 months though, and mobile enough to push up, roll around or otherwise free himself, a blanket should be fine for him

As much as I kind of hate to say it, but you might have to look into those blanket suits and hoping a muslin sheet is enough to comfort him for falling asleep. If all else fails you could bring him into your bed and co-sleep so you can make sure he's safe.
