No water or sand table here.
He played with toys in the bath, use a water table at toddler group and when big enough stood on a chair at the kitchen sink for water play. Sand he played in the sand pit at toddler group. We did make a stone tray for our roof terrace though, big tub filled with pebbles, gardening tools, trucks and diggers, shiny coloured treasure stone to be found or dug up etc, little wheel barrow he could fill with stones and walk around the terrace with. That was fun.
