Thanks! Astraea's not an ordinary baby, she inherited her mother's amazon strength.

Shaken Baby Syndrome, requires multiple short burts of rapid motion.
The fluid our brain floats on inside our skulls would hit the inside part of the skull, causing bruises to form on the back and front part of the brain as it rebounds from inertia, dispelling excess momentum.
gently throwing up and catching Astraea a couple of times is not going to damage her brain. and Clark's arms further reduced the sudden stop in acceleration by catching Astraea softly. batman would kick slam a kryptonite down Clark's throat if he fails to catch Batman's little girl.
I finally have a beta, adrianbdean.
thanks for reading.
