I haven't had no fucking sleep at all...

Maximus (my son who's 7 months) has been going on and off with sleep last night.. It's 4 am and I still haven't slept. Every 10-15 minutes he'd sleep but then wake back up.. What is going on? His head feels really hot and his nose is all stuff again.. Is he getting a head cold? I'm literally just crying because I am so tired. I try to sleep, couldn't. I put him next to me, he sleeps but then wakes up..... Like what is happening? What's wrong with my baby? 😢😢😢
