We bought this for my daughter for winter, and it's been fabulous so far. She's a little on the small side, so even at six months this is nice and roomy. She seems very comfortable in it, and it keeps her nice and warm (provided, of course, she's dressed in layers underneath). She also loves the fact that she is transformed into a stuffed animal and enjoys sucking on her "paws." I usually have her in it when I'm wearing her in the Ergo, and it seems great for that--not too bulky or anything. Just very snuggly.
