Normal?

Is it normal for a 6wk old boy to weigh 13.8lbs? He is extremely tall too. Was born at 8.6lbs 20.75inches. I know my doctor said you can’t over feed a baby as they will stop eating when they are full but I just wanna make sure I’m not causing him health issues. He is breastfed and formula fed due to medical reasons inhibiting my milk supply. Pic of my little chunks
