Read the original source →CDC's public-health guidance page describing typical preschool development: growing independence, storytelling, social play with other children, and new ways of moving and making things. It's written for caregivers, not researchers, and covers a broader 3-5 age band than GiftNav's own 3-4 preschool band.
Grounds the preschool guide's general framing (what a 3- or 4-year-old is typically capable of and interested in) in a credible public-health source, without implying any specific product produces these developmental outcomes.
Public-health guidance, not a study of gifts, toys, or products. Covers ages 3-5, wider than GiftNav's 3-4 preschool band. Describes typical ranges; individual children vary.
