A sleeping bag is very nice to use for your little one. It provides a sense of security and warmth. In principle, you don't have to use a blanket anymore, so they always stay warm because they can't kick it off themselves like with a blanket. If the sleeping bag alone is not warm enough or if your little one likes it, you can of course combine it.
