My Mil has her distant relatives (third cousin) daughter staying at her house for 2 weeks. She is spending lots of time with her taking her to town, different activities and restaurants etc. Relative is from another European country (don't want to be to outing with specific locations) and mil sees these relatives atleast every year, sometimes even twice a year. But she is spending alot more time and effort on this girl in 2 weeks than she ever has on my dc in his entire life (he is 18 months old). My DC is her only grandchild. AIBU to be a bit annoyed and puzzled by this? Why would you spend all this effort, time and money on distant relatives, yet hardly ever on your own grandchild.
