The size is listed as 50-70, 3-5kg, but it still fits my 2.5-year-old daughter who wears size 80-90. It might be too big for a newborn. It has been used a few times and has no fraying or stains. I think it can also be used for playing in the snow. It's also easy to put on and take off. I will compress it to make it smaller for packaging and shipping.
