Did your kids use a pacifier, thumb, or neither?

My oldest used soothies and wubbanubs. She was so, so attached to them. She still has them actually - "green binka" (frog) and "pink binka" (pink bear). I have cut the pacifier part off now obviously.

My youngest used soothies or wubbanubs for a few months then dropped them very abruptly - she exclusively and obsessively sucks her thumb! And only the left one for some reason..
