My DD1 is around 14.5kg and she'll be 4 next month. DD2 is 12.5kg and she's 2 1/2. DD1 is skinny and has always been this way. She's just so active that no weight sticks to her frame. DD2 has a belly on her but the rest is thin like her sister.

My MIL told me that one of my BIL's told her that he believed DD1 to be malnourished so I can understand how others opinions affect how you view your children. She is NOT malnourished in the least. She eats lots of food throughout the day (she's a grazer) but is always on the go. Too many people make comparisons to what they perceive as the 'norm' and in my BIL's instance, it was his comparison to his daughter who was always getting comments from doctors that she was overweight as a toddler.
