Doesn't sound safe to me as might get in the way of natural instincts to fit round each others bodies or cover baby's face. I am sure someone on here will pop along with a link to safe co sleeping guidelines. Baby needs enough space to breathe and wriggle a bit with no covering or squashing risks nearby. Hope you find a way to get a nap soon.
You don't want to baby sleeping with anything covering its head or face, or anything it can get tangled in. You might not roll on it, but the baby could end up with its face falling against the fabric.
I was always in bed and never would do it on the sofa. Perhaps I wasn't very clear but I used to do it with DS in the night when he wouldn't settle after a feed as he liked to sleep on my tummy so I felt it was a good way to have him sleep on my tummy with no chance of rolling off. And when I was on my side I wouldn't have been able to roll onto him as he was there! So co-sleeping really, but with him in a baby carrier rather than "loose" in the bed. I was always far too scared to co-sleep any other way and never had duvet over him because he would have had my warmth being so close to me. I was just concerned as none of my friends (who co-sleep with their babies) slept with them in a baby carrier
Is is safe to sleep with a little baby in a Baby Bjorn while you have a nap? I used to with DS, either with him on my tummy or me on my side. Is it safe? About to have another one and would like to do the same if considered safe.
