Directions Extensions
Challenge your toddler to throw things into the train. Challenge your toddler to push the train from behind instead of pulling it. Put something heavy into the train so your toddler can experience resistance. Remove the items to show the difference in strength required. Repeat and talk about putting things in and taking them out, about it being too heavy or just right.
