How much does your 3 month old weigh?

I’m a FTM and our 3 month old has been eating 5 ounces every 2 1/2 to 3 hours. We recently decided to start giving her more

B/C she fusses after every feeding. Will prob give her 6 ounces during the day and 8 ounces at night. We weighed her this morning and she was 13 pounds. Just curious how much you moms are giving your 3 month old.
