So, I've been reading many of the threads today, while I was painfully waiting to get 90k tech points...
I decided to play with the stews and made the one that gives a burst of energy. I could be wrong, but it looks like if I make my nursing mothers eat it, they run around (with babies in tow), even swim in the ocean, and gain + to building? lol ... ok, that's a new one.

Is this working as intended? Are they supposed to be able to do that? (not the + to building, but the fact that nursing mothers actually DO have a way to level up a little bit while busy with those infants)
