6let and M2 spent 5 nights with the ILs. My only rules were the kids use sunscreen and carseats. I told them we usually put them to bed at 8, but whatever they want. On the second night they were out late. FIL tried to tell 6let that it was 7:30 so he wouldn't get in trouble. 6let looked at the digital clock and informed him it was actually 9:24.
