Stroller rides can support a toddler's vocabulary development by providing them with opportunities to observe and learn new words in a natural setting. During a stroller ride, a toddler can hear and see a variety of objects, people, and animals, which can serve as a source of new vocabulary words. Additionally, the adult pushing the stroller can point out and label these things, providing the toddler with verbal input and helping to solidify their understanding of the new words.
