I think she was trying to get a sensible message across but did it poorly. The media - as the less intelligent media are bound to do (ridicule increases sales) - picked up on the 'consent' and 'nappy changing'.
But a few moments thought and you realise that mothers talk to their babies all the time. Or should do, anyway. We already know that babies understand far more than we realise, and everything that happens to them in the age from 0 - 2 is internalised as part of a complex learning process that eventually shapes their own behaviour, beliefs and ideals.
We know, for instance, that babies treated badly and who are routinely harmed and abused during that period grow into incredibly damaged and often dangerous adults. What the woman was trying to convey was the importance of setting an ethos - a culture if you like - where the baby learns that pleasantness, warmth and gentleness are qualities worth having.
I'm disappointed that the Mirror has stooped to the levels of the DFM but although she did it badly, what she was trying to put across was what all decent parents know and practise.
