Differentiate day and night baby

Aww man. I remember this vividly. Around one month old, i started to expose baby to sunlight, just hanging by the windows to see outside, so not direct sunlight. Helps with melatonin production which puts baby to sleep at the right times in the evening. Constantly did this for a couple weeks and she slowly shifted to sleeping from eleven pm, then down to ten then now at seven months around 8pm ish.

What I can say, sometimes it’s a phase. My baby used to be able to self soothed and fell asleep at night before 10pm. Now she’s 5months old and we need to pat her and hold her and most of the time, she sleeps at 12am 🥹
