I forgot that Daisy's sleep bag needed washing, I've just put the wash on now but I don't think it'll be washed and dried before she goes to bed so I'm going to have to try putting her to bed with a blanket... She hasn't slept in blankets since she was tiny, she now moves around her cot a lot in her sleep... What do I do to make sure she's safe and the blanket doesn't go over her face?
