A nurse is teaching a class about expected developmental milestones in 2-year-old toddlers. The nurse should include which of the following milestones?

A. At 2 years old, toddlers typically have a vocabulary of about 50 words, not just 20. B. Associative play begins around the age of 2, where toddlers play alongside other children and may start to engage with them, sharing toys and ideas. C. While 2-year-olds can drink from a cup, this milestone is more typically expected earlier, around 12-15 months. D. By 2 years, most toddlers walk independently, but this is more of a milestone for younger toddlers (around 12-15 months). E. Feeding themselves with a spoon is an expected milestone for 2-year-olds, as they start to develop more independence in self-feeding.
