Sleep regression

My son started the 4 month sleep regression early at like 3 1/2 months and it lasted over a month. He just turned 5 months last week and we got maybe a few days of ok sleep (woke up once late evening needing help with soothing bc of sleep cycle and once early morning to nurse then early wake up). However, last night he was up every hour. One time it didn’t matter if I fed him, patted him, etc he was wide awake for about 2 hours. Is this another damn regression already??
