3.5 Year Old Milestones: Storytelling, Hopping & Early Friendships
At 3½ years, your child is refining language, body control, and social skills. Stories get richer, friendships deepen, and curiosity about the world (especially "why?") takes center stage.

Common questions
It's a sign of healthy cognitive development. Answer simply, ask 'what do you think?' back, and use books to explore deeper questions. It's fine to say 'I don't know — let's find out.'
Yes. Imaginary friends are a common, healthy expression of creativity and social practice between 3-7. Engage with curiosity without forcing your child to acknowledge they are pretend.
Practice routines (handwashing, sitting for a story), visit the school, read books about school, and arrange short separations. Talk about feelings — both excitement and worry are normal.
10-13 hours per 24 hours, including a short afternoon nap for many children. Consistent bedtime routines and a screen-free wind-down help.
