You know there's a thermostat to place on the wall in build mode from the Seasons right? I didn't till mine were complaining about the cold inside. You then click the thermostat and set it to save money, or give more heat. That's besides the aspiration reward that you can get to bear the cold. That's one. The other, a toddler won't eat just like that. Look for a high chair in build mode, get one, place it, while there get the potty toilet near that too... You can be the toddler, click the high chair, ask for food, or to be caried to the chair, and then food. If he/she's done, ask to be let out, or just grab a teen brother/sister or parent and let them out. But yeah since they've no aspirations yet, and no rewards one drove me nuts last night. He's sleeping, but hungry already, feed him, oh he needs attention. That realism they went for there. So you know how it is in real life. Kids above that can be almost self sustaining compared.
