I am a triplet. But back in the day I was born there was no ultrasound. They had no idea my mom was not carrying twins plus one! So they let her carry us to term and be out and about.. kept telling her she was gaining too much weight yet allowed her to go full term! We were born at 5lbs-7oz, 5lbs-9oz and 5lbs-11oz. All healthy. We went home a week later I believe.
Yes, we were that big... pretty cool! In fact, all my sisiters and I always have had big babies who were full term... My eldest sister actually hadd a set of twins full term as well and they were still ehafty little thangs... So for all five of us, pregnancy is fine.. it's that part where you have to give brith that seems to be the challenge! LOL!
