I have 3 DCs, and since the eldest was born almost 15 years ago my mum has done nothing but criticise my parenting. Sometimes in front of me, but in a passive aggressive way, or to the children when they have the children without DH or I being there.
It ranges from all sorts of things to the girls hair not being in a style that my mum wants it to be in (for example they have plaits one day and she moans that it's not in a ponytail or vice versa), to the clothes they have, shoes they wear, to how we discipline them or even the places we take them to.
I consider that DH and I are good parents, we do our best, and I think my mum should support me to parent my children as I wish, or at least keep her mouth shut if she disagrees so much.
It's got to the stage where I get nervous when I see my mum with the kids as she'll basically pull apart their appearances and find fault with everything.
