Dear Care and Feeding, My son “Xander” is going to be turning 5 at the end of May, and I’m not sure I can go along with the type of party he wants. Xander is obsessed with all things poop emoji thanks to my dumbass husband turning him onto them. He thinks they are the funniest thing in the world and he wants to have a poop emoji-themed party. Think poop emoji games, decorations, and even a cake that looks like one! My husband is all for it; I am not—I think it’s disgusting and inappropriate. Should I put my foot down, or do I indulge this immaturity on the condition it’s a one-and-done? —Put Off by Poop Dear Put Off,  Wow. Cake, too, huh?…
