Give me all the tips.

Currently my little one has been fighting her second nap pretty hard. Today she fought it so hard that decided to just go with the flow ( we generally follow that rule anyway- co sleep/bf on demand/ blw) however up until now she was pretty good about 2 naps.

She fell asleep in the car on our way home from getting food around 545, well I decided not to wake her. Ive resettled her once with boob. But I guess she will just sleep through?? How does this work.

For reference she had her morning nap from 10-11am. And yes I tried to put her to bed at 2, then 3, then 4 and then of course she falls asleep in the car! Advice/ help/ encouragement please!
