I don't want to come across as a Debbie Downer. But she is in for some shock. Don't get me wrong as a new FTM it is fantastic, best Job in the world, there is nothing in this world that you would not do for your kids blah blah blah.
I'm the most positive optimistic person and thankfully haven't been effected by PND, but even without PND it's still hard. She'll struggle to keep up the facade of everything rosey in the garden. as someone who's baby just sleeps and eats i still find it feckin hard and admire anyone who has multiple children, children with disabilities, challenging behaviour, colic, reflux etc
