A Facebook post about suggested bedtimes has moms and dads up in arms as they argue for earlier, later or no guidelines at all, reports Good Housekeeping.

But not everyone agrees. “I think this chart is ridiculous,” one person responded. “11 p.m. is not an appropriate bedtime for anyone at any age. The latest bedtime that I think is appropriate (for normal days, not on holidays or special days/nights) is probably 9:30 p.m.”
