婴幼儿发育里程碑 (2个月到5 岁)是了解宝宝发育的重要线索。请勾选出您的宝宝达到的发育里程碑。每次儿童体检时带上这个里程碑参照表，与医生讨论宝宝已经达到的发育里程碑和下一阶段的里程碑。Milestones matter! How your baby plays, learns, speaks, acts, and moves offers important clues about his or her development. Check the milestones for your child on a regular basis. Take this handout with you to the doctor’s office and talk with them about the milestones your baby has reached and what to expect next.
