Infant/Toddlers needs Declined While playing another lot

New vanilla game. Hired a Nanny before parents left home. Infants needs dropped into the red. He's caring for himself.

I've just had this happen a few days ago.  It's an active career Detective, whose wife is a Freelancer so I could have her home with the twin infants they have.  When he returned, the infants were on the floor beside their cribs with needs in the red and his wife was watching TV.

The next morning I had him hire a nanny, even though his wife would be at home, thinking that might solve the issue.  Nope, when he got home the infants were again on the floor beside their cribs with needs in the red.  The wife was actually standing in their room doing nothing for them, and the nanny wasn't even on the lot.  The nanny did return shortly after the detective got home with the same "glad to see you again" message they give when hired again.

I play on PC and have never used mods or cc.

Sorry if this is duplicate.

Can't travel if I have an infant being left in their house with the parents present. AKA not in daycare. The only needs filling was energy. Hunger, Fun, etc is in the reds. I have everything except Lovestruck.
