Theres no woohoo option in shower and bed, and my toddler cant sit in highchair.

@jraeb10 Going to move this to game issue as you reported multiple issues in one thread and will need to split them out anyways if these can't be solved with troubleshooting.

So troubleshooting first:

1. Woohoo: did you try multiple Sims couple to see if it's an issue with the couple for some reason ? There is an issue where Sims suddenly become related so check if that's the case for you.
2. Does it look like a reset ? Did you try selling the high chair and getting a new one ?
