I am and it's tough but it gets easier the older they get. I have a 7 month old and a 4 year old. The issue is that you are just so darn tired when they all get to bed and then you have the whole set up ordeal...
I earn brownies by doing nice things for my wife and then look at getting away to other IIS members properties for observation. I am also planning to get away to ASV's dark site in the next few weeks and am considering Snake Valley in November.
To be honest with you I live in inner Melbourne so even on moonless nights I am restricted to planetary observation or checking out a few binaries/clusters.
It does get easier, one of my strategies is to predict a clear night a few days ahead and try to get as much sleep as possible in the lead up to clear night so I can put the kids to bed and not fall flat on my feet after it. I usually set up on given night befoe getting into my 'chores' so the scope can cool down and I have my tables set up, eyepieces selected, targets for that night selected etc. Catching up on sleep beforehand will usually stand me in good stead for a 3-4 hour session which is worth it. Again, it's all about balancing time with the family and time with the scope, brownie points work a treat. The older the kids get the better they sleep
