Both parent Sims have become stuck when talking to their infant Sim. The only way I can tell they are stuck is hours have passed in game and the Sims are in the same spot until I cancel the talk to interaction, which then cancels the whole interaction queue.
Both parent Sims also failed to feed the infant Sim when instructed to do so. I was more likely to be successful if I told the parent Sim to pick the infant Sim up and then feed the infant Sim, but often the infant Sim is picked up, moved slightly, and put back down.
I see the same behavior described above when attempting to putting the infant in the crib as well.
