I am really upset with my mum (again). She has always had a preference for her first born grandchild which is my sisters. I have never begrudged her the attention or given my sister any upset for the way she treats my sisters 2 children to the way she treats mine. My sister has the oldest Grandchild who is 8 and No. 3 Grandchild who is 4. I have No. 2. who is 6 and No. 9 who is 2 - way down the pecking order for attention. Ever since my No. 1 grandchild has been born my mum has had them regularly for sleepovers from a matter of being a few weeks old. She now has both of my sisters children regularly at weekends for sleepovers - my daughter is 6 and has slept at my mums once!! My sister has been with her partner for 10 years and they have recently split so obviously wants to get out and about a bit more and my mum is looking after her children every weekend - whereas when I asked her to have mine for a night so that I could go away for my birthday she said no. My MIL/FIL have always been fantastic at looking after our children for the day but are both in the late 60's/early 70's - so it's really hard work for them and have never wanted to do a night shift - but doesn't bother me as they are so fantastic at other times. But feel totally hurt by my own mum as she obviously prefers my sisters children to mine - as she wants to spend more time with them and doesn't seem to careless about mine. My DD has asked me why her nanny loves the other 2 children more than her and I have told my mum that - but she doesn't seem to realise that she is hurting my DD. Was looking after my nieces yesterday and my mum had to come and pick them up from me as she had them for the night so my sister could go out - and she doesn't seem to care that my DD had been playing with them all day and now they are going to nannies and she's not. My mum has never been one for confrontation and I have never been able to talk to her about it. Does anybody else get this with their mothers and the first born grandchild.
