No longer sleeps through?!

Emma • 5/19/17, 3/16/19 👶🏻👶🏻

Help, I’m losing it. My son has been sleeping 7p-5a for over a month. Now suddenly he’s screaming crying multiple times a night. Anyone else?! Eventually I’m going in and soothing/feeding him but he doesn’t seem hungry or to have any other needs. He sucks his thumb and has been self soothing for months.

What’s going on?? He turned 6 mos on the 16th. I teach in the morning and I am dying here.
