Its fuckin great.
I was a bit of a house husband for a while a few years back ... it certainly beats sitting in front of a PC all day. Enjoy the nappies, the accidents, the smells, the shite, the sleepless nights etc.... those days are over all too quickly.
My domestic situation didn't work out and now I only get to see my lad during school holidays (they live in Jersey now) and weekends when i can afford to fly over there.... I can't believe he can ride a bike without stabilisers now - and i missed it !! Boo Hoo....
Enjoy it mate.
Treasure it.
