Waiting for my son to completely fall asleep so I can roll him back onto his back. He will only fall into a deep sleep on his tummy :( Hopefully he knocks out soon I'm exhausted 😴

Is this chicken pox?
He has eczema on his shoulders, but the rash on his back is different, appeared last night and he now has some on his neck and chest too.
Help!
Ok question I went into check on my 2 year old son and he was blue his face was pale and his lips were blue and his eyes were open. So I put his crib railing down and rubbed his chest and he took a big breath then started crying. I took him out and was holding him and he kept trying to fall back asleep. Then he started shaking. He was not cold cuz he has his warm jammies on and he dont have a temp. What should I do?
Yesterday I went out with my boyfriend went to watch a movie, me and him don't live together yet. but point is yesterday when he was dropping me off his like sleep over at my house witch the mom and dad lives. I said no,
his response was why is everyone deciding or making choices for you and their going to do the same with the baby, when I know that's not true. what he thinks is that my mom tells me not to sleep over. So he left all mad. and I felt in my heart that he went on and cheated on me...
Outrageous!
A 5 year old was detained and questioned at his school for taking a toy gun to show his friend. He was so scared he wet his pants and his parents weren't notified until 2 hours into the questioning. He was suspended for 10 days, but it was reduced to the 3 days he had already served after the parents and others complained. The school stated that the situation was handled appropriately and would be handled in a similar manner in the future.
My 7 week old baby falls asleep faster and sleeps longer on his tummy. Which I have read he shouldn't sleep on his stomach. I'm just wondering how bad would it be if he did.
