The nature of being a regressor in Stardew Valley is that the Junimos will absolutely delight over any little one that they run across, and tend to gravitate towards them.
They like to trade little gifts with them at first, appreciating whatever the little one brings them (fully understanding that being given their best shiny rock is a huge honor). And eventually the Junimos will lead them away to a secluded part of the woods where lots and lots of Junimos are waiting to play with them (though they are sure to lead them back home when playtime is over, of course).
