It all depends on how much time your wife likes to spend at the field
Where have you moved all the equipment off too?
Up until about 1 they don't cause much trouble.
I'd build at the dining room table as I had time.. 30 min here. 1 hour there..
Pack up everything, clean and put it away till the next break came along..
Yes I don't have the time I had before to go flying but as they get older the kids will want to tag along..
About 5 is when I felt I could safely bring one of the kids to the field and not cause trouble. while I was flying.
I've picked up a few park fliers that I fly with the kids on a buddy box... They love em and it's a new area of the hobby for me.
