Very detailed I hope I can get an answer 😩😢😢

Marie • Hello, my name is Marie, I'm 27 years old and I joined this website the moment I found out that I was pregnant. This is my first pregnancy and I'm praying for a 100% healthy baby boy or girl 😊
My son is 8 weeks and I noticed probably once every 2 weeks he goes through this episode of breathing fast, being really fussy and difficultly going to sleep. Other symptoms is very alert, jittery, panicky movement and constant spit up and body getting sweaty. I am dying to find out what's going on.. Does anyone have any answers.. If so what's a solution?
