Safe for 6 month old?

As long as the mattes is firm I think it will be fine
As your pediatrician tho

That seems pretty safe to me as it’s got quite a lot of room to move about and I don’t know about your baby but my baby is quite still and wakes up pretty much where I laid her down and she’s in a next to me crib so if your baby doesn’t scoot too much or roll too much then I’d say it’s okay but if you’re worried check with your paediatrician

If it says it’s a cot AND that it meets the safety standards for your country then yes x

depends on the mattress you get!
