We have two kids (aged 6 and 2) and both work full-time, so I know that I shouldn't expect to get lots of time together with all of that going on. However, I realised recently that we were probably only getting about 1 hour per week (split into 10 minutes here, 20 minutes there) when we were spending time together without the kids. My wife tends to go to bed (to go to sleep) at the same time as the kids and wants to sleep for 9 or 10 hours. It makes it very hard to get any time with her.
I've mentioned this and she has tried to have lunch with me once per week and maybe have a bit more time in the evening, but it seems like she feels that I am asking for a bit much. I realised that I don't know how much time other parents of young kids get to spend together. Any input is very welcome!
