Developmental Health Watch

Because each child develops in his own particular manner, it's impossible to tell exactly when or how he'll perfect a given skill. The developmental milestones will give you a general idea of the changes you can expect as your child gets older, but don't be alarmed if his development takes a slightly different course. Alert your pediatrician, however, if your child displays any of the following signs of possible developmental delay for this age range.

• Cannot throw a ball overhand

• Cannot ride a tricycle
• Cannot grasp a crayon between thumb and fingers
• Has difficulty scribbling

• Doesn't engage in fantasy play
• Resists dressing, sleeping, using the toilet
• Lashes out without any self-control when angry or upset
• Cannot copy a circle
• Doesn't use sentences of more than three words
• Doesn't use "me" and "you" appropriately
