Baby weight?

Mia • 21. 1 daughter. Baby boy otw ☺️

Okay ladies i got another growth scan today. Last time i went which was 3 weeks ago they said my son was 12oz. Almost a pound but not a pound. Today he was over a pound. He was a pound and a half. And they said he was still petite but all my <a href="">pregnancy apps</a> say my baby is suppose to b a pound and half so I’m confused. I have another growth scan coming up
