Do you always go for to "Top Notch Infant" and "Happy Toddler" traits?

I've had some great luck when it comes to earning the Top Notch Infant. Sadly, despite how well my Toddlers do, earning threes and fives across the board, nobody has managed the Top Notch Toddler. This used to happen all of the time. I take little to no credit, though. I play my game with autonomy on full. Life span on Long. My Toddlers all just do their own thing with very little prompting on my part. They're just great kids! What can I say? I suspect their not having earned Top Notch for Toddlers is the bug mentioned? I just thought they'd left it out, since the Infants now can earn it. I should really stop assuming stuff. you know?
