Drop nap?

At what age did your LO drop naps all together? My daughter is 22 months old and has fought her nap so hard. I had been following 6/5.5 tried shorter wake times tried longer wake times and still she wouldn’t nap unless I put her in the car and I have another baby on the way so I can’t put both kids in the car every time she needs and a nap and don’t want to get her in the habit of that. She has been sleep trained and has went down for naps and bed independently since 8-9 months old. I have been consistent with our sleep training method and she has always went down easily for naps until the last week or two. She still does great going down for bedtime but has refused naps. I feel like she’s not ready to be done with naps since she falls asleep in the car but I’m not sure what else to do anymore.
