I bought my daughter these ELC stilts to help with balance and coordination.  We call them plant pots, they are red and look very much like up turned plant pots with long strings attached to each to hold with the hands.  I think they are good fun to play with, although they do come out from the play cupboard that often and haven't been used as much as I hoped.

The stilts are made from hard plastic and are about 5 inch high.  The are round with about a 6 inch diameter at the base and about a 5 inch diameter and the top of each stilt where the feet go.  The strings, which are white plastic costed rope, are attached through two holes in the top on the  stilts and you need to hold the strings tight to keep the stilts on the bottom on your shoes, otherwise you the stilts will be swinging around and don't to land upright.  Therefore the hands and feet have to work together and you need to pull the right hand up to keep the string tort as you lift the right for etc etc.  This makes for quite a lot of coordination for a small child, but at four my daughter really got the hand of these.  

They say they are not suitable for kids under three, which would be right, there are too many coordination skills involved for little ones. I bought these for my daughter when she was four as I noticed she wasn't good at balancing on beams etc. at the park and thought these would help, which I think they did. My daughter would pretend she was in the circus and I guess they will be of interest to my kids until they are around 6-7 years old. Perhaps afterwards I can adopt them as plant pots, after all they even have holes in what would become the base!

You may need to alter the string handles as they will be no use for a child to hold onto if they are too long.  This is easily done by tying an extra knot in the rope on the inside of the stilt.  Otherwise they are a very simple and straightforward design.

I think I paid £4 so these are not at all expensive.  They are good for helping children with balance and coordination skills and can be really fun so even if they haven't been used all that much I am still glad I got them.
