Please tell me I’m not alone

I’m not sure who cried more last night, my 17 month old son or me. We are going on 3 weeks now of middle of the night wake ups and they are progressively getting worse. I try not to go into his room so he can him work through it, but he cried for 30 minutes last night before I finally went in to place him back down. In all it ended up being 2 hours of trying all the tricks in the book before he eventually went back down. Each night I can tell my patience are dropping and my frustration level is rising. He used to sleep through the night until 630 without making a peep and now it’s bloodcurdling screams. Ugh make it stop!
