He and Ronan Scott enjoyed an afternoon meeting in Hamilton, NJ while their moms enjoyed one of Sarah's gourmet lunches (mmm...pistou!).
This was apparently Ronan's first run-in with a newborn - he was a true gentleman, letting Luke get in a snuggle with his Mom...
...And he gave Luke some thumb-sucking pointers while giving him a gentle rock in his car seat.
Luke has also had some quality time with fellow Hoboken resident and trendy hand-me-down provider, Ben Kornbluh.
They had a baby summit in Luke's room, where Ben convinced Luke that he should make his activity mat work for him.
Ben was unrelenting in his assertion that the mat is a happy place - once you learn to control your hands.
