Sounds to me as if she was honest from the start,
She had the children, brought them up well, didn't abuse/ill-treat them in any way.
And has waited 'til they are old enough to deal with it before going public, and I'm pretty sure they would have discussed it before hand.
Having lived with/been married to a Midwife for the last 30 years I'm certain there are a hell of a lots more women out there who feel the same way.
He's on about the mother who publicly said she regretted having her children. There are many like her but most of them keep it to themselves. As they should.
