The end of the toothless grins

We have a tooth!  At 27.5 weeks (almost 6 1/2 months old), Isaac's first tooth just broke through.  So far, just a little extra fussiness but no fever or anything yet. So, I am thinking these will be the last pictures of the toothless baby's smile...now on to the next milestone.  Each milestone is kinda bittersweet for me.  You look forward to them, but then are kinda sad that they are growing up so fast.
