These are Mahlon's and Sara Beth's 4-D sonogram pictures at 27 weeks. They were about 3 lbs each. Mahlon is the one on top, then their tangled legs, and Sara Beth and her smooshed face are on the bottom. She has been a hard one to photograph. This week (31 1/2) they are about 4 1/2 lbs each. They are very active! I go back on Thursday for my 32 1/2 week checkup and my doctor said they should be about 5 lbs each by then.
