Resisting Second Nap

We are on day 3 of resisting second nap! We have been on two naps since 7.5 months and we’d have a hiccup here and there but would always get right back on track.

I have tried to get LO down for her afternoon nap for about an hour and a half now and she just won’t go down. She will be 1 on 2/22. Anyone else going through this? I want to try to stay on two naps for as long as we can, this has thrown me for a loop.

TIA!
