I have a 13 month old son, he was born at 37 weeks at 6pds, 2 ounces. He is now 19pds, 9 ounces and appears to be heathly and happy. He is small for his age and is not even on the chart for his weight but his height is fine. He eats all day long and drinks lots and lots of milk and has 8-10 poopy diapers a day. Is this to many? is that many poopydiapers normal? I quess im concerned that he eats so much and still is underweight.
