Napping help! 😫

My daughter is about to turn 1. She used to be a pretty good napper, only taking like 5 minutes to go down. She sleeps a full 12 hours at night and will take a morning nap around 10:30 and an afternoon nap around 2:30-3. However, recently she has been taking 30+ minutes to go down and she will only sleep for 45 minutes to a hour each time. It’s hard to take so much time to get he to sleep and then wait for her to wake up two times a day. Is this her way of telling me she’s ready for 1 nap now?
