How much should a baby add monthly?

How much should a baby add monthly? Anyone interested please read the post and answer in the comments. All good day?‍♀️. Time flies by quickly, children grow fast. On October 21st I as a responsible parent took my child for a scheduled checkup at 1 month. The checkup lasted 5 minutes (but about that later). We were weighed and measured: weight was 5530 (minus 200 grams) - 5300 grams, height was 60 cm. As a result we gained around 2 kg, grew by 7 cm. A jump so to speak. How did your first doctor's visit go, how much did they gain in the first month?
