Dd1 is best friends with the little girl next door - there's an 18mth difference between then, dd1 is nearly 4, her friend 2.5. They're a nice family and we've always got on although the mum can hold some strong opinions about other people's parenting and isn't scared to share them.
On Friday, both our dd's were at this dance class together and then messing around excitedly together afterwards, running around and refusing to put their raincoats on. We were both getting a little exasperated, and then other mum turns to me and says "my dd only does this because of your dd". And then if I hadn't already heard the first time, she repeats it.
My dd absolutely adores her little girl. Yes she's older, and when they get together they can both get rather exuberant but they had also just spent an hour being encouraged to run around and weren't doing anything in my book that I would class as 'naughty'. They were excited and happy to be playing with each other.
I am really pissed off with other mum for implying that my dd is responsible for her dd's behaviour. But they are our neighbours so I need to be very careful about how I deal with this.
What should I do?
