I haven't seen that many treasuries with baby items in them. If you really want to get in more treasuries, you should probably join a treasury team. A lot of them use other team members items when making treasuries. Of course, personally I haven't seen that much traffic from most of the treasuries I've been in, so I don't know if it's that big of a deal. Of course, if you get in a treasury that makes the fp or something, that would be awesome, but I wouldn't worry about it too much.
