My sister is 17 (just). I see her once a year for definite, maybe another odd occasion if my dad brings her up. I never hear from her. I gave up a long time ago trying to get her to come over or contacting her as I wouldn't get replies. Clearly we are not close.
I don't think she could tell me when the kids birthdays are, she has never acknowledged their birthdays in any way nor does she ever ask about them, she isn't a 'child' person and when she has been around, I have tried to encourage her to talk to them and she says she doesn't know what to say. She is an 'urgghhh babies' person.
Today, randomly, I got a text just saying "can I take X (DC2) out to X" No mention of DC1 who is older and easier to look after.
I know a couple of years ago, one of our cousins would let her and her mates take his son out to this place. His son was probably around DC2s age, probably a bit younger (DC2 is 3.4). Cousin has always been happy to fob his DC on anyone who would take him though and I thought it was odd at the time as they aren't close either but I never said anything.
It only seems to be little ones they (and I mean sis and her friends as that's who it would be) want to take because they are small and cute. I would trust DC1 who is older and more trustworthy but DC2 is at a running off stage, turn around DC2 has gone, doesn't come back when called and is definitely going through the stroppy 3's stage.
AIBU to have said no? I haven't had a reply. I am guessing she isn't happy about it but I am not sure I care. DH agrees with me. Sis doesn't know DC2, DC2 knows who she is but that's about it. I know I was younger than sis is now and taking her out and looking after her (big age gap, I could pass as her mother) but I was always older than my years anyway and trustworthy. I don't really trust her and her friends. I am not saying they will do anything but I don't think they have any idea of how to look after a wilful/bolting/occasionally stroppy 3 year old.
