Baby sleep help!

Hayley • Mum to 2❤

My little girl is 4.5 months old and she sleeps with a blanket however has become really unsettled and only settles if she has a bit of our duvet over her and then sleeps through (shes in a next to me crib) is there any way I can give her her own toddler duvet and reduce risks whilst doing so if you know what I mean?

Please no bashing im a first time mum just trying her best x
