Sleep Regression at 13 Months. Heeeeelp me!!

My son is 13 months and has started regressing at night and with his naps! I’m dying! We usually perform his nightly routine and set him on his bed without a hitch. Now he cries bloody murder when I set him down. Honestly, I feel like people think we are torturing my child at night. We let him cry for 10-15, but he nothing. Then, when I finally get to his bed, after he falls asleep kn my bed, he wakes up twice in the middle of the night and refuses to sleep in his bed! He does the same with his afternoon nap. My husband and I dying here! Any suggestion?
