Daycare blanket [ca]

Our daycare let us know that we need a warmer blanket for our 2.5 year old. We’re currently just using a microfleece blanket we got when she was born. So a bit thin and a bit small.

What are people using? I was considering just getting a crib duvet from ikea (which is what we use at home) but it seems like overkill. Brands and links appreciated.
