Hello everyone ❤️ Girls, how many daytime naps have you had in our age…

Hello everyone ❤️ Girls, how many daytime naps have you had in our age range? I can't figure something out, it seems like my son started changing his schedule... We used to have a stable 3-4 daytime naps, but now. At 10 am wake up, at 10-11 pm went to night sleep. Now he wakes up at 10, but sleeps only twice during the day, I can't understand if this is normal? And goes to bed at 9 hours at night. And overall, his sleep has been bad for several days. Yesterday woke up at 4 am and was awake almost 1.5 hours. They barely put him to sleep
