Aww I am sending good thoughts and prayers over your way!
Kingston will do fine! Try not to worry that much, I know its hard bc its your BABY. We have all been there, and we are here for you!!
Sometimes the tech's will call you and let you know that everything is ok after he is done..( I told them to call me after Peanut's sx) Maybe if you haven't already...You should call them and tell someone to call you as soon as they are done with his sx so you know everything is ok
