Size of my babies

Troy was fairly small when he was born. He was 2890g or 6lbs6oz and 47cm or 18.75 inches. Whle in the hospital he lost weight and went down to less than 2000g. To make sure that the baby girl is not going to be as little as him we did a weight estimate on her today. She is now 2300g which is about 5lbs, so as long as she stays where she is for a little bit longer she will be bigger than her brother. With Troy getting Nec when he was born, I have this obsession about wanting her to be as big as possible.
