Swaddle to sleep sack sleep

Just switched my daughter onto no swaddle last night she slept pretty good in her sleep sack but she usually sleeps 9 hours straight wakes once and goes back down for 4 hours after eating. Last night she went down at 11, woke at 3, back down from 4 to 8 and then back down from 9 to 10:30. So not quite 10 hours. I expected her to not sleep quite as well at first since she’s so used to her swaddle, but she’s only getting half hour naps, maybe 3 a day right now so I rely pretty heavily on those extra two hours at night. Has anyone been in a similar situation with a good sleeper and transitioning out of a swaddle? Did they get the hang of their new sleep sack or suit? Did their naps get longer or did night time sleep go back to normal? She’s 19 weeks tomorrow. Thanks!
