I think most of the parents here would understand this topic. We have 2 kids who where born 2 years apart and when our first child was born, the sleepless nights started and lasted for 2 years then our second child was born and the sleepless nights continued for another 2 more years. I was literally a caffeine zombie when it ended. I mean being a father is really a great experience but without any family members to help, it was quite hard since I was also working full-time and my office was far away, so I needed to leave early and get home early to help my wife with the kids. When I arrived at night, I would hurriedly prepare dinner and let my wife sleep while I take care of the kids. I became a master in bottle sterilization, mixing baby formula and changing diapers, my wide would wakeup around 3AM and I would sleep for 2 hours only daily for years. My only Naptime is on Sunday, when my mom visited I'll sleep for about 6 hours, while she tends the babies.
