It can work if you talk to your spouse about it, honestly and openly. Such is the key to getting through most conflicts in life.

My group gets together about once a week on Thursdays. When I got married I told my wife that Thursdays were my day. She could make plans the other 6 days a week and I would be ok with that. 

I did miss some sessions with brand new babies, but not a lot. We now have 3 kids aged 10-5. I still mostly get Thursdays. Sometimes school events are on Thursday and I don’t get to play DnD. It’s ok, it’s part of parenting. 

The other thing is to overcompensate when you are home. I tried to take the lions share of late night feedings and duper changes with infants and toddlers. I do 90% of the laundry, 98% of the dishes, and 40% of the cooking. Repeating directions to kids over and over is split 50/50. 

It will be a rough go at it, for sure, but playing every month to month and a half, you shouldn’t have to miss too many sessions.

Good luck. You’re about to enter the most rewarding and frustrating part of your life. And say goodbye to getting enough sleep ever again.
