Super easy and free Montessori-inspired DIY threading material! Threading materials are great because they require the child to use both hands together at midline. Since he has to steady the spoon it is a bit more challenging than stacking the paper towel roll pieces would be on a vertical dowel. Simply cut up a paper towel roll (or toilet paper roll) and model threading onto the wooden spoon. Every child is different for the best time to introduce. Yitzchak is 16 months old.
