What the heck does this mean?

Whenever you ask Henry what his name is, he says "Dada" and laughs hysterically. I have a bracelet that says Henry and he reads that as Dada as well. I thought he didn't refer to himself yet, other than to say mine. Now I realize that he puts Dada before most things: Dada spilled, Dada's brush...Should I interpret this as "There's a spill and There's a Brush" or "Henry spilled and Henry's brush?" What a nut.
