I'm seriously thinking about trying an experiment. Some say we can still have the chicken nuggets without the high chair on the lot. I'll have to see if that's a fact. The other side of this experiment will be, if we do need the highchair for that kid-favorite meal, I'm going to see if I can have the highchair placed underneath the staircase, or if that won't work, in a basement/or attic.
On an aside, I believe a thermostat, if you have Seasons, should be added to the lot to help regulate hot and cold better. It's found under Electronics.
