Wonderful update!! Yay Joshua!!
My daughter was a 28 weeker and I know exactly how great it is when you look at that scale and it says 7 pounds!!
As for development, follow Joshua adjusted age for everything....he will most likely even follow his adjusted age for weight. Adjusted age is calculated from his due date. So, just pulling numbers from the air here...if he was due on August 10th, his adjusted age would be 8 days old. If he wasn't due until August 22nd, then his adjusted age would be whatever gestational age he would be. Make sense?
