Swaddle

Hi mommies! When does your babies stop using swaddle to sleep? My son is going to 6 months but he still sleep with a swaddle on. Tbh its hard to find a swaddle large enough to wrap him because hes all chubby and long nw. Haha. I have tried all ways to make my son sleep without being swaddled but he keeps waking up after 15 mins. He will get cranky each time i put him to sleep without it as he couldn’t sleep properly. Do you mommies know what i can do about this? How do i stop him from using swaddle to sleep?
