5 month old sleep

So, my son just turned five months. He used to sleep perfectly before the four-month sleep regression. He would sleep 11 hours every night without waking up. Then the sleep regression hit and we got through it but now he is still waking up multiple times a night. He woke up 12 times last night. He is still swaddled because he can’t go to sleep at night without it but if he wakes up at night and gets mad he breaks right out of it 🙄 do babies just never go back to normal after the four-month regression? 😩
