Hello there,
There's no need to worry - Electronic Arts are always working on fixes to their games and expansions,
I have had this bug as well, simply go to Settings, go to Gameplay tab, and turn off Autonomy, then turn it back on, this will reset actions they're planning to do. This resolved the issue for me, if it continues after this, simply restart the game and use another sim to do actions on the toddler.
Hopefully I helped!
