It might seem a bit odd that blowing bubbles is during a PT session, but most of the session start with bubbles, which helps calm down Josephine upon first sight of Lana (poor PT is gonna get a complex!).
Josephine still has trouble rounding her lips (well, she doesn’t do it at all, actually), so the fact that she is able to blow bubbles TWO separate times is certainly a milestone in my mind. While standing independently no less!
