Massive size difference!

When they were born, Lilly was 3 ounces bigger than Kate. At their last dual weigh-in, they were exactly the same. 23 pounds 12 ounces. That was in September, though. Lately they've had stomach viruses and pneumonia, and I know they have lost weight, so I don't know what their 2-year visit will show (2 weeks from now) weightwise. They've always been within 1/2" of each other in height.

 

at 3 years old, Ethan is 12 lbs heavier and 4 inches taller than Tony When they were born, Ethan was 1lb 1oz heavier and 4" longer than Tony.

 

At birth Nathan was 3" longer and 13 oz heavier. William caught up in height quickly, but is still 6lbs lighter than Nathan. Really scary is the fact my 20mo is only 5lbs lighter than William (23 mos apart). The big boys are the same height and have always been within a 1/2" since William caught up.
