That is normal to have family take more priority than car hobby. I went thru that when my daughter was young. When she was in high school she did not have much interest in the hobby, so we did things that she liked. The kids are more important than the hobby. Put it on back burner and spend time w kids. I didn't spend much time on car hobby until I retired. My job took too much time, now I am getting things done with them and enjoying it.
