Titled "Children Will Listen", TVTome lists it as airing April 17th, but show no new episodes the 27th, or April 3rd or 10th, which I don't think is right(I know the 27th is all new)

Anyway... here's the description:

One of the housewives is pregnant. Bree and Rex send Andrew to a rehab clinic and is put into a counsleing session with troubled teens and their parents who discuss their regrets. One of the housewives gets in touch with their biological father that they haven't seen in a long time. Susan's mother, Sophie shows up on Susan's doorstep when -- like mother, like daughter -- she encounters trouble with her current boyfriend.
