We did 2 weeks of 'every other day' - one nap one day, two naps the next. Helped them adjust.

Classic 2-1 transition. Usually happens 13-18 months. Push wake windows longer in the morning and you'll naturally drop it.

Don't drop until at least 13mo - they regret it if you go too early.

If they're getting solid 2hr in afternoon, the morning is on its way out. Bedtime might need to shift earlier for a few weeks.
