Dh has a friend 'John' who he met 10 years ago at work.
John and his partner 'Mary' meet up with us every 6 months or so.
We have 3 year old DC and theirs is a year younger, aged 2.
They chose not to put DC in nursery as Mary's mum moved in with them and is pretty much a live in nanny so can cover them while working and give them a night off whenever they want.
My DC has been in nursery since 8-9 months.
Mary doesn't agree with nursery before age 2 and I've noticed each time we meet she always asks 'Remind me what age your DC started nursery again?' 'How many hours a day is she in nursery?' And observes DC a as if scanning for signs of damage.
We don't see them that often and I got on with John long before Mary was around on the scene but I find the questions/ judgement so annoying.
I know many on MN agree with Mary and yes in an ideal world we'd do nursery later but DC is doing well and we don't have live-in family help like they do.
Women like Mary are why I avoid mum friends in general as can't stand the judgement you get from women who think they are superior mothers.
