My 10-month old son wore this for his Halloween costume.  It was adorable, and we got many compliments.  I was hoping the tummy would be stuffed, but it wasn't, however it was still cute.  We didn't use the blanket that came with it--not really sure why it's part of the costume.  My son seemed very comfortable in it, and we liked that the bottom had snaps at the legs so we could change his diaper easily.  He started to chew on the part of the hat that was near his mouth, so I unbuttoned the top snap and he stopped.  I wouldn't recommend this costume if your child is walking because the feet don't come off and I imagine it would be hard to get shoes on.  It was in the 60s outside during Halloween, so we just had him in a onesie and socks underneath.  The instructions say to hand wash, but I threw it in the washing machine on gentle cycle and it was fine.  I let it air dry, though.
