i know babies are flexible but it looks so painful! last night SO was holding dd with one arm.. never an issue until last night... she launched her self backwards, he had her good with that one arm but i thought her head was going to touch her toes! it looked so painful! then she just did it to me, sitting on my lap i was holding her and she wanted to go i guess... she threw her head back and she bent over my arm! i would be in so much pain if i did that!
