My oldest child is not NT. My MIL has not ever paid much attention to him. She comes to our house and only engages when it suits MIL doesn’t know him and doesn’t seem to care.
My youngest child is NT and bright to boot (not that the oldest isn’t but has had intervention and support to help him access the curriculum) which MIL loves as she was a lecturer and thinks that academic performance is the height of everything (even if the person doesn’t actually ever do anything afterwards with it or their life in fact)…
Aibu to feel a little aggrieved that my MIL pores over the youngest, even instructing my oldest to ‘share’ his stuff (they share when necessary but it’s never necessary as the youngest will never miss out and I feel it’s more because of preference). Aibu to also slightly laugh when my oldest keeps calling her by a much more generic name than what she might be considering the fact that she is their grandmother?
