The Hola Push Along Train Engine is a great way to encourage crawling and early development skills. It is suitable for children 6 months of age or older and is a great way to encourage early development skills like hand-eye coordination. As the train moves, your child will learn how to push and pull objects. The gears rotate inside the train, teaching your child about cause and effect. The little bear on the train will spin around, while the smoke from the train will billow up and down providing your child with visual stimulation.
