I just skimmed through it MG & I'd not have her in my kids lives at all...
I cannot understand why she'd try to get your DD to wear her christening gown over your DH's who is DD's father... FFS the woman is a wlaking fruit loop..

Personally I'd just say here's whta we are doing, no planning, no helping with plans etc, here's what is happening end of story show up if you can & if not No big deal!

But she sounds like the wicked witch from the West!!!!
