text: TALK WITH YOUR PEDIATRICIAN ABOUT HIS WEIGHT, AND VOICE ALL CONCERNS. BUT DO NOT STRESS ABOUT IT.  THERE REALLY ISN'T A SET TIME A BABY SHOULD WALK, ALL BABY'S ARE DIFFERENT. MY DAUGHTER WHO IS 8 NOW, WALKED  WHEN SHE WAS A YEAR OLD AND MY SON WHO IS THREE,  DIDN'T WALK UNTIL HE WAS 15 MONTHS. JUST DON'T WORRY!!!!
