This is just a "hats off" to you parents! I just spent less than 2 days with my niece (7 years old) and nephew (4 1/2 years old), and I am exhausted!!!!!! I get 2 days off and then they will be back, this time with my other niece (9) and nephew (12). They are totally sweet, spirited but not overly rambunctious or misbehaving (well, boy gets cranky, but he's 4), only loud sometimes (not all the time), not grabby at all, and they don't argue about going to bed. And they like to read!!! So these ones are pretty darn easy, and I am still exhausted!!!!! Just a shout out to those of you who do this full time!!!!!
