So we needed a sensory tub that would be appropriate for a one year old. I just knew if I put her in front of the beans she would plop a handful in her mouth! Instead, I poured some Cheerios into a pan for her. She loved them! She was able to pour and touch (and yes, eat!) to her heart's desire.
We actually built a little wall out of kitchen chairs so that each child could have their own play/work space with their own materials. So far Amy hasn't learned how to scale the chairs, although she does enjoy standing next to them, watching what Isaac is up to.
