Considering what boundary breaches both of them, and especially Lottie, have experienced, Louise doesn't worry about it too much. It may be a bit patronizing in her opinion, and she doesn't approve, but at least it is in line with the mood and kept to a bare minimum. She may say something if he tries again at another time.

For now, she's just glad that he doesn't prod further and gives Lottie time, and thus settles down and wait for the child to relax enough to set her down.
