I’m really nervous and probably will get little sleep tonight. Any advice?

Update: we just started last night and it was alright but he woke up and won’t go back to sleep. He hasn’t cried but he’s just wide awake now which never happens he always goes back to sleep. I’ve been awake a few hours and probably won’t sleep the rest of the night. (Morning)

Update 2: lol ok I got him

Back to sleep but it’s almost 5 so I might as well stay up. I just hope he starts sleeping longer. The past few nights he’s been sleeping from 8/9 to 5:30 am so I hopefully he gets used to that.
