The information is divided into the following age ranges: (1) prenatal; (2) birth to 4 weeks; (3) 1 to 3 months; (4) 3 to 6 months; (5) 6 to 9 months; (6) 9 to 12 months; (7) 12 to 18 months; (8) 18 to 24 months; (9) 2 to 3 years; (10) 3 to 4 years; and (11) 4 to 5 years. For each age range, a summary paragraph introduces the information, followed by a listing, with explanation, of behaviors parents can expect from their child at that age. Sidebars contain "Tips and Things To Watch For" and "Notes on Brain Development." (EV)
