Big baby already!?

So this is my second kid.

I arrived at my new doctors today and we of course were concerned about how big he is and if I'd go early.

My son came 2 weeks early fully grown and healthy. At 8.2lbs and 21 inches.

So we were told this baby is big as well. By the measuring of my belly.

The doctor said he weighs 4lbs.

I'm only 29 weeks 1 day.

He's suppose to be 2.5lbs according to this app..

Am I in for trouble?

If he's already a pound and a half bigger than he's suppose to be.
