my favorite app that I have used is what to expect. they give you all kinds of information of what's going on in your belly and how big baby should be.

I have a doctor appointment tomorrow, I wonder if they can give me an idea. I have never been told his approximate weight.

Around 3-4 pounds is what I think I read. All pregnancys are different. My son was at 3.25 pounds at 30 weeks and 2 days
