Only sleeping 2 hours. HELP😭😩

Megan

My 5 month old is only sleeping 2 hours at a time and at this point I am exhausted and completely OVER IT. Around 4 months he went through his sleep regression where he was up every 45 minutes for like a week after that he was giving me 4, 5 and 6 hour stretches. I could see the light! Now hes up every 2 hours again and I am soooo tired. If I put him down at 7 he’s up at 9, 11, 1, 3, 5, then 7. Any tried and true tips or suggestions? I’m not a proponent of crying it out. I do let him self soothe in his crib but what normally happens is he just gets even more agitated and harder to get back to sleep. 🙄😳
