Hi Lanna,
Thanks for looking into this for me. I very much appreciate your trying to help me with this! However, when I logged in this morning it appears the glitch may have fixed itself. The original glitch still happened where I lost the first baby and had to redo the quest, but the non interactions between the sims and the new baby have corrected itself.
I was able to age the baby that the sims weren’t responding to and then I adopted a new baby and put her in the bassinet. The mother sim went straight to her and picked her up and I was able to do the first baby quest and collect the prize for the event and once I completed the event the mother sim still interacted with the baby by picking it up and feeding her so I’m hoping this is a good sign and that I’ll be able to keep enjoying the game at this point. Thanks again for your help 🙂
