Jeannine is teaching Marlene to walk. 

"Oh, very good dear, you're doing great."

(Hopefully the boys won't get jealous).

Henri doesn't seem to mind in the least that she focuses all her attention on Marlene at times, he seems more entertained with his toys, and is in no hurry to learn to walk.

What about Jean? Will he care? Heaven knows. He always seems to be thinking about his music and the songs he'll compose, but he's still a teenager, though not for long, in fact he'll be going to college soon.

Yes, like her brother Bradley, Jean is about to become a young adult, both are more mature.... Well, except for the silly traps they set all the time, like the one now waiting on the chair in the garden. Jeannine and Tony don't fall for them anymore, they've learned, lol.
