My 6 year old DD1 seems to be rude and cheeky to my DM for no reason and I really do not know what to do about it.
DM takes DD1 swimming once a week after school and picks her up from school once a week. But DD1 has suddenly started to be really horrible to her. Last Friday she apparently screamed and shouted at her and called her 'evil' and said she hated her all the way home from school (DM had not seen another boy push DD1 over and said she did not know if it really happened). DM was really upset about it but told me not to make a big deal of it with DD1.
But then last night after swimming, when DM dropped DD1 off at my house, I witnessed DD1 repeatedly saying 'Granny is naughty' and 'It's all Granny's fault' when she got told off for throwing hair bobbles all over the living room floor. When DM told her not to throw them, she said 'You can't tell me off, Granny'. She generally continued with remarks like this - 'I don't like Granny', etc. - while DM had a cup of coffee with me and I could see DM getting more and more upset.
I kept telling DD1 to stop saying such horrible things and tried to make her realise it was naughty but she wouldn't stop. Eventually DM left and I had a very serious talk with DD1 about how hurtful she was and how DM would be very upset now.
This morning my DF emailed me to say DM had been very upset when she got home last night and had even cried. He said she's thinking of not taking DD1 swimming anymore or picking her up from school anymore.
I am horrified at DD1's behaviour and feel so sorry for DM who is lovely and really things DD1 doesn't like her now. She has done nothing to deserve such treatment, and is a real help to me generally as I work full time.
I don't know what to say to DD1 to make her realise the effects of the things she says. She seems to not care when she upsets DM.
I'm just feeling really sad about it all. I have wondered if it is something to do with her feeling jealous about attention DM gives DD2 (18 months old).
Any advice will be appreciated!
