Congratulations! Your child now has developed the hand eye coordination to stack the rings. Don’t put away the stacker just yet. You can repurpose the toy for more advanced fine motor challenges using rubber bands
1. 13 months+
Use rubber bands which have larger holes so the child doesn’t need to stretch the rubber band to get them in.
2. 16 months+
Use cloth rubber bands which are smaller in size and need to be stretched a little
3. 18 months +
Small plastic rubber bands
