No, it absolutely isn’t. What Lexi wants is to be let alone, not pestered about how big she is or is she taking enough exercise or eating enough.

Surprisingly, the childless Lynda seems to have worked this out, whereas Jennifer (who must have gone through it herself, particularly when carrying Adam) has not.
