Can we say 3 babies?!?!?!?!!

Ok, so WOW... my sister got a shock last week. Well, actually it took all of us by surprise! =) My sister and her hubbie Zach, have a 1 1/2 year old named Addison. They found out they were pregnant again right around the 4th of July (which actually the picture I posted of their family is from the VERY DAY they found out! =) ). So anyways, she came up and visited Sam and I last weekend, etc... and she had her four month checkup on Thursday. Well, when she came to visit we both thought she was looking bigger than she did with Addison, but they say that since your stomach muscles are already stretched out, most people show sooner in their second pregnancy.
Well, at her four month appointment, she asked the doctor if there was any chance at all she was having twins. Because my sister just felt so much bigger already than she did with Addison. So the doctor listened for a second heartbeat and found it! She was like "Yes, you are having twins!" So my sister was surprised, and they took her to the room to do an ultrasound so that they could check out the babies. Well, they start the ultrasound, and my sister isn't having twins, she's having TRIPLETS. Yes, TRIPLETS! The doctor was amazed and asked if she could call the staff in, b/c this was the first time they had ever seen a patient get prego with triplets that hadn't used fertility drugs. I guess the chance of it happening are 1 in 900,000!
Prayers that she has a healthy pregnancy and healthy babies! On a side note, they do know that at least one of the triplets is a boy! In a few weeks we get to find out the sexes of the other two =)
