Have an 8.5 month old. The socks DO stay which is a HUGE PLUS, but the advertised sizing is way off.  They are too small.  They are a little "girly" in appearance with the round circles but if they stay on that is more important to me.  Will get one wear out of each pair before they are washed and then done b/c they are too small. Will try the next size up and see if any better.  Only other complaint is in the packaging - there are 2 plastic ties in each pair with very little room to cut so lots of little plastic pieces to make sure you pull out of the sock so they don't wind up in baby's mouth and have to be uber careful not to cut the sock when trying to cut the plastic tie.
