Coming back from the birth is tiring (and this isn't even with the boy being home!). Chances are you're up at least once a night with your wife for various things. Last night it was to kill a giant spider that was lurking in the bathroom waiting to pounce on M and turn her into Spiderwoman. But alas her valiant husband got out of bed and killed it with a flip flop! Most of the time it's for support and help as she's trying to pump. Yeah guys you will be helping and this goes on every 2 to 3 hours, so just be prepared.
But in the end I made it through the day. The boy is fine the wife reports, I'm not as tired as I was at lunch (could have slept the rest of the day) and I will go back to work tomorrow. When he comes home I'll be taking another week off as I suspect that will be as stressful as the last week. Some people have commented that the lack of sleep continues for the next 18 years. I hope not, but if that's the case so be it. Only a week in and it's been an incredible journey that I wouldn't trade for anything else!
