The "breaking maternity leave" hasn't come out of the Duchesses mouths. And it isn't about how she's had to pop into work for a KIT day but there's no childcare and the kids need to get to school and the washing machines broke. It's about the much more basic thing of not wanting to hand over the baby for X hours just so you can stand around whilst the press judge how fat / thin you are, how lazy you are to. Have not been at the other event a week after the baby and a whole host of comments about how you've swanned off out for a nice day whilst the Nanny is stuck at home with all the children.
It's perfectly acceptable for any new Mum to not be eager to do anything that involves hours away from their new baby.
As for Meghan, I think it's probably unwise making any statement on how long she wants off until the baby is here. Yes Americans have very short leaves in general. But that doesn't mean that if an American woman had the capacity and finances to have longer off she should.
Lets face it. Shes be sagged off any way.
Returns to work 1 month later - showing off, trying to shame Kate, thinks she's getter than us.
Returns to work after 4 months - lazy good for nothing freeloader who thinks she doesn't need to work for her privilege
Returns to work after 9 months - guilty of treason, probably a sign they're going to get a divorce, poor Harry, let's behead her.
Takes baby - show off attention seeking braggard trying to shame Kate
Leaves baby - heartless witch who shouldn't have had kids if she wasn't intending to look after them
