My son is going to be a 1 year old this Friday. He’s weighing in at 17 lbs and a few ounces...he also looks very small compared to other 1 year olds. Should I be worried? He’s not walking or really talking either. He says some vowels and words like dada or mama but he saying them like he’s just making sounds. He eats snacks throughout the day as well as baby food mixed with rice or oatmeal. I don’t know what else to do. His pediatrician doesn’t seem too worried about it.
