What!!15.7inches?!

Lisa
So i havent really been taking much notice of the length of baby for a while now on this app, until my hubby said how big is she now. I looked at it says 15.7 imches (30 wks) and he got the tape measure out. Oh my ! How is there something that big in me? Slightly freaked out now! Is that arms out stretched to toes or what it doesnt seem possible!!!!!!????
