I had a friend having scans every fortnight to check on her twins progress & they were pretty right with their weights, but I've also seen alot of women on here who've had the scans completely wrong, so they definetely aren't reliable!

As someone has already said, its not very often at all that your body will make a baby you can't birth. Its not the way mother nature works. Obviously there are exceptions, but you've birthed 2 very healthy sized bubba's already without any complications, so there is no reason you can't birth a third.

There are quite a few babies born on here recently that were 10lb & more. I know someone whose DS was 13lb born & she birthed him vaginally.

Have faith in your body It does know what its doing!
