This is very interesting. We have a 6 year old and a 20 month old, and (for reasons including various bugs and the phases of the moon) one or both are waking up at least twice on your average night. We very occasionally get a night where they both sleep through but we're talking once a fortnight here.
As my wife currently has a bad back, it takes her forever to get out of bed. Consequently, when the youngest wakes up and screams, I'm always the one that goes at the moment as (if I left it to my wife) our eldest would wake up due to the noise by the time she got there. It's been this way for 6 months now. I must say I'm pretty shot to bits for the most part, and I've certainly struggled more with my control than I did the middle part of last year when everything was perfect. I actually cope with too little sleep reasonably well. It is broken sleep that kills me off...
Enjoy your sleep, Shane! If you go down the route of children in the future you'll look back on it with fondness
