We bought her this rings stacker for Christmas. For 6 months this toy has sat in the background waiting for its day. That day has come. It is like a switch flipped in her and she is now obsessed with stacking rings. I just watched her take everything off so she could get them on in the right order.
Now I’m not saying this is FOR SURE a fact, but it is possible that the appearance of these Thomas the Train Engine PJ’s (from Brady, Jake, Dane and Ben) may have brought a special power with them. The special cousin stacking power.
