Nap Schedule

We are having a rough tough with the nap schedule lately. My 17 month old has always been a great sleeper. And her naps and sleep time were always very predictable. Lately it’s been an absolute nightmare. I️ thought she was transitioning from 2 naps to one. So we tried that for two weeks. She was the crankiest she’s every been- before and after the nap. I️ couldn’t handle how miserable she was acting. And it seemed to be affecting her night time too- she was waking up several times and whining and crying in her sleep- which she never does. So we decided to go back to two naps a day, which we’ve been doing successfully for 4 days. Of course today she’s been yawning all morning- I️ put her in for her nap and she’s wide awake!!! And it happens to be in a day I️ need to run errands in the afternoon. This unpredictable schedule is making me crazy and making it impossible for me to get anything done. I️ feel like I’m trapped in the house just waiting for this girl to nap all day. And my husband is away for work for the next two nights so I️ really feel alone and stuck in the house. Anyone else having a difficult time with napping at this age? Any advice???
