We just had our first child 4 weeks ago. Relationship with sleep has completely changed. Before I'd need ~8hour of straight sleep to feel completely rested, anything less I felt like my brain was very sluggish.

4 weeks later that number is 5-6 hours.

Also relationship with coffee has completely changed. 4 weeks ago drinking a strong ~16 oz of coffee in the morning would keep me up all night. Now I drink multiple cups throughout the day and can pretty much sleep at will :)

Sleep has been very light and dreams not super vivid, every now and then will fall into a vivid dream but not lucid

Falling asleep is instantanous
