We're joining Kim (aka wntg1grl), a stay-at-home mom of three who's expecting twins, on her exciting journey from bump-to-babies. Check back every week for the latest developments. 

Week 13
What's Happening with Mom:
I had an ultrasound last week. It's surprising how much my little ones grow in just two weeks.

They did confirm once again that these are fraternal twins (or "roomates" as the doctor calls them). They are each separate from each other with two placentas and two complete sacs. He also says that as far as twins go, this is the best case scenario because they are not sharing anything but my uterus. That is welcome news.


I was a bit surpised to see that I am still loosing weight. Another two pounds gone. We aren't worried because there is NO WAY I am getting thru this pregnancy without gaining some weight.

My boys are being so great. They have slowed their pace to keep "up" with me! My husband, Donnie, is wonderful. When he gets home from his long day at work, he takes the kids outside for some much needed exercise -- frisbee golfing, bike riding, or just to the park. He is the most supportive man, especially knowing that we are having twins. I really didnt expect him to be the strong one.

My second son, Casey turned 7 this week! We had a party at a local BMX track. It was great.

What's Happening with the Babies:

We're completely formed -- our faces, our tiny toes, those kissable thighs. During the rest of pregnancy, everything will grow to proper size so that by the time we're born our organs have matured enough to make us capable of living independently.

Question of the Week from Answers:

Has anyone taken Zofran for morning sickness? -- brittanysmom87

StarLee: It didn't work for me at all. I know other people who have had success with it. It just did nothing for me.

Danielle720: My doc put me on Phenegren first, and it worked wonders, but it also knocked me out for hours. So the doc switched me to Zofran. It isn't as strong, so it worked moderately well but didn't make me as tired.
