Another Milestone...

This Sunday, Jack hit another milestone.  Every milestone he has completed has brought me joy and pride.  This current milestone brought me to tears. We transitioned Jack from his high chair to a booster seat at our dining room table.  He's been in a booster seat before at restaurants, but seeing him sitting at our table, I admit I got a little misty eyed.  I'm getting chocked up just thinking about it again.  What is wrong with me???  I told Bryan about my feelings when he was sitting at the table playing with a puzzle and he admitted that it bothered him a little as well.  I think a part of it is that high chair has been in our dining room since Jack started eating solids at 6 months when he was just a baby.  When. He. Was. Just A. Baby. I (we) have suddenly realized our baby is no longer a baby, but turning into a little boy.  How and when did that happen?!
