In the rules for Evil Baby Orphanage, it says for Bad Toys that "you may discard the toy from your Orphanage to cause any Evil Baby to take it's Unsupervised Actions during your Activity Step." Does this mean that I can discard a Bad Toy to make another Time-Nanny's Evil Baby do their Unsupervised Action during my Activity Step? The people I play with have assumed up until this point that you could only do this to your own Evil Babies, but in rereading the rules, this isn't actually clear. In fact, the word "any" seems to indicate that this can be done to other Evil Babies. The ability to cause other Evil Babies to do their Unsupervised Actions seems like a very powerful ability and would drastically change the flow of a game.
We discovered that we initially thought it only applied to your own baby because the player cards are worded differently than the instructions. They read: "you may discard the toy from your Orphanage to cause an Evil Baby to take it's Unsupervised Actions during your Activity Step." This was the original cause of our assumption; this doesn't seem to indicate that you could target other Time-Nanny's Evil Babies.
