Mine 18months wakes up every hour🥺.at 14months we cut 2naps to 1nap a day 1:30-3hrs bed time 8pm I tried late bedtime but still same issue waking up every hour.mostly I offer her water at night and she sleeps back.
My daughter wakes up multiple times too for milk. I transitioned her to 2 naps in the day from 1. She slept a little later but slept throughout the whole night!
My son has 1 nap in the noon and still wakes up in the middle of the night at least 2 times for bottle, I tried offering water but it's a big no. 🥺
