Here I sit on the cusp of my career: proud, excited, ready. And sad. Since he was born I’ve been one thing primarily: his mommy. The majority of my days, my weeks, my time belonged to him. Come Monday that will no longer be so. Come Monday I will enter the final phase of my transition to ‘teacher’. Come Monday my days will no longer be ruled by his nap schedule. The sound track of my life will no longer be his cartoon of the week. I will no longer eat my lunches with him on my lap, and I will no longer chase him around our living room to feed him his. Come Monday I will stop being a stay-at-home mom. I will start being a teacher. And even though I’ve worked so hard to get here, that still breaks my heart a little.
