Weaning off swaddling

L 👶🏼🤎✨

Soo I didn’t swaddle my 12 week old last night for the first time ever and wow it was rough. He woke up every few hours when usually he only wakes up once. Should I not have went cold turkey and slowly weaned him off instead? Anyone been through this? I just ordered a sleep sack also so that should get here soon.
