[GRO] Sims freezing when teaching infants to sit

This is happening for me as well.  They just stand there frozen - I have to reset the sim each time.

Adult Sim keeps holding infant indefinitely, when directed to practice sitting. If I cancel that action, they autonomously go and put infant down in crib upstairs even if they stand beside playmat downstairs! 

HI dee15644​ 

no, patches can't be uninstalled.

Please try the clean folder approach described here: 📓[GUIDE] Clean User Folder Approach | EA Forums - 12690428 

can I uninstall this patch?

the option comes up but it freezes and empties the cue never practicing sitting

Could you please provide some details what happens ? Do you not have the option ? Do they never learn it ?
