Only one nap

Kira • Wife 👰 Engineer 👷‍♀️ Mommy 🤱 9/8/16 💖 5/21/19 💙
When can I expect my baby when to only take one nap per day? Is your LO doing this?
She only took one long one (1-1.5 hours) for past three days in a row but I'm wondering if this is a phase or it will stick. She's always switching things up.
