I did notice that when Robyn FINALLY made her grand entrance to the graduation, Meri took Solomon and was interacting beautifully with him. It was striking to me, as we've so rarely seen her smiling or happy about anything lately. But she bounced him up and down, and then when he was facing her, then when he was sitting on her lap facing outwards, she was playing with his feet almost as though she couldn't keep her hands off of him.
It really surprised me, because I'm firmly in the "she doesn't want another baby" camp. She sure does seem to like Solomon though . . . so, yes, WHY does Robyn need a babysitter? Unless they're both "at work" together. Probably sitting around in a restaurant with Grody, dreaming big dreams and planning furniture arrangement in the new houses, and laughing at how gullible Janelle was to share her inheritance with the family.
