Hi I am looking to buy a gro snug. My baby is due on 19th July. I have loads of gro bags for when she is big enough so dont want to spend too much on gro snug which she might not use for too long. Do you think I should get gro snug cosy or gro snug light? Do you think a snug light and I can always add more clothes or a tucked in blanket if I need to or a snug cosy as in this country it is rarely super hot? Thanks
