Have I mentioned that smiling is my very favorite milestone? Out of every milestone, there's nothing that tugs at my heart strings more than those first real smiles. The kind of smiles that light up a room. The kind with a sparkle in their eye. The ones that become larger once hearing mama's voice. The ones that will keep any adult or big brother doing the same thing over and over again to elicit the same gummy grin. Yup, smiling is my favorite.
