I dont trust the charts. They had Tucker pegged at 7 pounds as an adult. You cant always go by the size of the parents either.
When Tucker was 4.5 months old he was 5 pounds, I honestly didnt think he would grow to much more, since he came from 4 pound parents. BUt I was wrong..
He continued to gain weight untill he was around 8/9 months old where he reached 9 pounds and has stayed there. He is solid as a rock and not an ounce of fat on him. He is my little muscle man..
If your little one is already at 4.5 pounds, at 13 weeks, he will be on the bigger side, probably 9/10 pounds. More to love..
