I have 2 girls my brother has one. As it's the easter holidays my parents are planning a daytrip with niece. My dds aren't invited. My Ps have had dn to stay almost every weekend since she was a few weeks old, while b and sil go out. I feel (probably wrongly) that I'm owed some babysitting from them, but it doesn't seem to be offered so readily. My other brother buys comics for dn, nothing for my girls. My mum holds a bank account for dn and has put a few hundred in it, not for my girls. This is because dp and I have started savings accounts for our girls while b and sil spend all their money. See, there's a reason, and I understand it, and attention is lavished on dn because her own parents are so preoccupied with themselves, but, even so...
It's late, and it's bugging me, because when it was mentioned about this daytrip, when I suggested that they could take dd along too the reaction suggested I was taking some sort of liberty.
