For Christmas, my mom sent our daughter the Boogie Monster Dance Kit, and we have had such fun with it!
The kit contains a book, a music CD and a set of Boogie Monster legs:
Yes, they are shaggy orange leg warmers. And my kid says, "Put on my Boogie Legs!" whenever she sees them.
The book is a fun read with a nice rhythm to it, and the text suggests different moves for the child (and parent, if you're so inclined) to try as you read along. The CD is a fun, non-grating set of songs to help you and your little one get your groove on.
It's a great way to spend some time with your favorite small person doing something active without even having to leave your living room. I think kids age 18 months to 4 years are especially well suited to the Boogie Monster's ways. Give it a whirl!
