More Awesome Than You!

Here's a bug I've noticed (Generations) and it irritates the snot out of me.

I like having a Sim with the Daycare profession.  So the toddlers grow up, and eventually they're coming home from school with my child and teen Sims.

Now here's where there's a problem...the Sims in my active household can't interact with them.  The only interaction available is "Stop Doing That."  Other than that, nada.

It seems to be only the daycare "graduates" with that problem.

Anyone else have this problem?  (Anyone else masochistic enough to deal with half a dozen toddlers?  LOL)

EDIT:  I do not have this issue with premade children, such as Sandi French and Sam Sekemoto (the ones my Sim gets to watch if I start her out right away).  These are kids from families that have just suddenly moved into the neighborhood.
