BOY MOMS I need advice!!!!

So my fiancé and I are having a boy this July ♥️ and we are going to have him circumcised .... how does that process go? Because I feel like I won’t be able to watch someone go up to my son with scissors and hear my son cry and how long does the healing process take and what do you have to do after the process is done? Please give me any advice you can! Thank you
