S.K.
a Wagon. we have the step 2 radio flyer one. in the bottom there are some drain holes. there is one in the center - it fits an umbrella pole in there. we did that with both my kids.... 1 kept them off the sand - and the eating of sand to a minimum - kept them in the shade. put a bucket of water in there for them to splash around in. also provide a place that she can stand up on the outside and still hold on to the side to walk around (both my kids were standing and starting to furniture walk at 8 mos, and full walking by 10 mos - so they loved to be able to walk around the outside of the wagon too.
