Jer left for work this morning, and kissed us goodbye. Jack was still asleep, but raised his little arm and waved. Jer laughed but on his Fb said it was a little sad. Most of the time Jack stays asleep with no response, so I think he's coming out ahead!
He's been waving and saying "thank you" after our Home Depot trip last week. When the orange aprons would go I would say thank you and as we moved on Jack waved and said "thank you". Sadly people move on so quickly, they often miss his goodbye.
