Molar progress

I feel like poor leiland has been working on these two year molars forever. Today he's super cranky so I checked them out and found progress. His left side has been farther along then the right side for awhile. Today I could actually feel the tip of one of the cuspids right at the surface. It hasn't broke through just yet but I can actually feel it. No other have made noticeable progress but this is a big deal to me. I hope they come quick. His left side always gets them quicker where the right side tends to lag and take forever to fully come through.
