I thought moving to one nap meant longer naps??

Just cold turkied my 13.5 month old to one nap after she started taking 30+ minutes to go down for naps.

Her old schedule: 3/3.25/4, with naps being capped at 1.25 hours

Her new schedule: 5.25/5.25, with naps being capped at 2.5 hours

We surely thought she’d be tired enough to nap for at least 2.5 hours but she’s consistently waking after 1.5 hours. Is this just the adjustment period or am I doing something wrong? I’m worried she’s not getting enough daytime sleep.

For what it’s worth, she did great transitioning - she seems alert and playful and is happy when we put her down and will fall asleep on her own in about 10 minutes.

Edit: just in case someone reads this in the future and is curious, she started napping longer! We sometimes still get 1.5 hours but it’s starting to trend more towards 2.5.
