Just curious if anyone knows the stats on that one?

Actually, I don't know if this is correct or not, but I just got my weekly pregnancy update today and it said that it 60% of women have their babies before 40 weeks. That sounded really high to me though, since I thought that most 1st time moms actually went past their due dates. So, that's my input...not sure if it is accurate or not. This is from Pregnancy Weekly, by the way.

Wow. That's a great site for information! Thanks for pa__sing the link along!

Thanks JessDT for that website.....It is a very good site. According to that about 3.5% of women have their babies (naturally) at 37 weeks; 9.5% have them (naturally) at 38 weeks; 18.5% at 39 weeks, and then I belive it said close to 30 % will have them the 40th week. So, Nora 1 it looks like the 60% is pretty accurate. when you add up those percentages ( and round up)......its close to 60%. anyway, thanks ladies for your input.

I was actually just reading something about that today. I read that 60% of all babies are born before their due date. Unfortunately I don't think I will be lucky enough to not go overdue. It seems to happen a lot in my family.
