MIL (ds1 step-gran) has a "secret tea" with my ds. I don't allow him to have sugar in his (decaf) tea, but they have a little secret where she gives him sugar in it and they don't tell me.
Ds1 has asked me a few times for sugar in his tea and I've refused. She knows this. She's been there.
Dh thinks this is a sweet little bonding secret between them. I think it's out of order as I'm the mum and I should have the final word and it is never okay for my 9 year old to have secrets from me. He's not quite mature enough to ascertain between an innocuous one and an important one I think, iyswim.
I do know sugar in tea isn't the end of the world. I know she's not asking him to keep a sinister secret, but I think the secret keeping and undermining me here is the issue. Not the sugar in the frigging tea.
AIBU? The whole thing has me quite upset tbh, especially when DH is giving me shit for not thinking it's cute.
