Same as mine!!! Will sleep at 10pm then wake up at 11pm and will only sleep back to 2am. Maybe can check your environment? My baby stop waking up and sleep through when I start switching off my laptop. Hahah. I used to leave my laptop switched on overnight cause I’m used to listening to videos to sleep. Now we always switch off the laptop before putting him to sleep and he’ll sleep through till 8-9ish
When my son was 2 years old . he used to wake up mid night and play. now he is 4 years old. now he is sleeping at night
