does any one know of any kids gymnastics clubs in sheffield for little ones (4yrs).

There is one at don valley stadium, they have a beam and a A-bars, and vault but limited floor work facilities. The coach seems to be very competant and good with children.

There is also an Acrobatics tutor who I highly recommend (I attend the adult class when possible). Here they concentrate more on floor and trampoline work.

You may want to consider a trampoline class (ponds forge) as well. All three complement each other very well.
