I miss sleeping but I wouldn't go back

Pre-kids me slept 8 solid hours every night, took naps on weekends, would stay up late just because I could. Now with a 2 and 4 year old I'm lucky to get 6 hours and it's broken up. Coffee has become a personality trait at this point. Sometimes at 3am when I'm walking the floor with my youngest I think about those quiet nights. But then she falls asleep on my shoulder and I remember why I'm exhausted. The tradeoff is real but it's worth it. Anyone find a way to get decent sleep though? Asking for a friend who is definitely me.
