Sleep regression

My son hit 4 month sleep regression and he won’t sleep for the life of him! Im so frustrated, I do the whole night routine and he not relaxing or getting sleepy, he fights every night but today it’s at the max.. 2 hours trying. I’m at my limit and don’t want to be mom anymore! I hate it

I don’t look forward to nothing, to hard having to deal with someone else’s emotions and being responsible
