Hi everybody:)
Firstly I wanted to say thank you to the community! From my first days as mum googling safe cosleeping in the middle of the night, this reddit community gave me so many answers/suggestions and encouragement:)
I wanted to ask if anyone had similar situation…
So now my LO is 3 month, we cosleep , but also have a cosleeping bassinet next to me . First stretch of sleep she often does in bassinet, so I go to bed a bit later and can stretch my legs and have a little rest, and once she wakes up we sleep in C curl rest of the night. But we have queen bed, and as soon she will show signed of rolling I won’t be confident with the setup we have.
Have anyone tried to do sidecar crib for ikea Malm bed? There is an annoying wooden lip around the mattress, and not sure what we can do with it. I kind of feel our options are only to try with sidecar or complete disassemble the bed frame and have mattress on the floor (my husband would not be happy with this option, but can’t risk her rolling of the bed). Any recommendations would be very appreciated!
Thank you:)
