My baby is almost 9 months and she sure is very active... she moves about freely in bed, is able to sit up in her cot bed, can even stand up in her cot bed. Now here’s the thing... it’s getting to winter so the weather is cold. My baby does not like anything restricting her from moving about when she wants to, so she hatesss wearing her gro-bag. I have tried using her baby blanket but she can easily fling it out of the bed as obviously its small. I have heard that quilts or duvet shouldn’t be used until baby is one year old... so what do I use in this case? Please advise.
