So I've been experiencing this issue on one of my games. There are no babies in the house, just one person and their pets. I've tried reseting sim, shower, and after that didn't work I tried selling the object and buying a new one... didn't work... tried buying a different one... didn't work... I've searched through a couple different forms now and it seems this has been a bug going on for some time now and has hit a decent amount of people... Honestly I'm getting really tired of all the bugs I've been running into on sims 4... EA I now highly suggest you actually fix your broken issues in the game before continuing to put out new content for it. With this many issues and bugs, you're going to, and I've already heard you have, loose previously very loyal customers. No one wants to play a glitchy game.
