yes normal

Is that common that my youngest child likes to be a baby at home, but she likes to act like bigger sister at daycare? She likes to especially act like big sister to those boys of her similar ages, hold their hands, pat them, and like lead them to play/do somethings, and normally those boys are clueless and let her do it. Girls are chatty in her class, probably boys are more quiet and socially behind compared to girls. She is almost 4, in a class of age 3/4.
