Need advice with sleep

My son started having wake ups at night when he turned 11 months..I thought it was the 12 month sleep regression kicking off early and maybe it was, who knows. Anyway, it started off he would wake up once a week....then twice a week....and so on. Typically he only wakes up once, I rock him back to sleep (I know I shouldn’t) and then he sleeps til morning. In these past 7 days he woke up 5 of them. 2 of the days i had to go in twice to put him back to sleep. This is honestly getting exhausting..

He wakes up at 7, naps once at 12:30 for 2.5-3hrs, bed at 8pm. Should I cut his nap down to 2 hours? Change nap time? Idk what to do. I don’t want to let him cry himself to sleep..I just can’t do it..but something needs to change 😩😴 I thought once I went down to 1 nap, he would sleep great through the night but it got worse..
