More recent milestones for our son at 13-14 months of age: his dedication at First Baptist DC with Rev. Julie Pennington-Russell. (As Baptists we don’t baptize babies but we do have a dedication ceremony where the infant is presented to the congregation with prayers.)
Also his first times visiting a Smithsonian museum (Natural History) and the National Zoo, standard must-visits for any DC-area resident.
Another milestone: his first time in a swimming pool, the shallow kiddie wading pool to start. (I’ll spare you the photos of me in trunks for this one.)
