I was looking for a blanket sleeper that wasn't made of polyester and couldn't find any. That's when I found these Baby Soy winter organic footies. They are thicker than their usual ones and incredibly soft. They are pretty TTS... I bought 6-12M for my 4 months old. It is pretty big on her, but she can still wear it now. It will for sure fit her for a while. The feet are a good size (my DD is tall and many of the footies on the market didn't fit her feet - I'm thinking of Gap, for example). It is really cute, comfy and warm. I still use her sleepsack over it, but I know her arms will be warm too. The only con: the way it buttons up, it tends to open in the crotch area. But the many pros make me forget about this detail. And less buttons makes it easier for the middle of the night diaper change. I strongly recommend it.
