This is actually an historical AIBU and I don't know if I was BU at the time.
A few years ago I had my second baby. I also had a two and half year old son who really struggled with the birth of the baby. His behaviour was really challenging, just running around, screaming, throwing things: all within the normal toddler range but hard work nonetheless. He was at home with me and the baby for different reasons (didn't go to nursery etc) so it was tough.
One day a colleague (Jenny) said she would call out to see the baby. When she was in my home, my two year old was running around squealing, throwing things...attention seeking stuff. My son has well and truly passed this phase now BTW!
Anyway a few days later I bumped into a different colleague, Martina, who asked how it was all going with two. I said it was tough as my eldest was struggling. 'I know. Martina said he was crazy'. It turns out that a group of the had been out for a meal and Jenny told them all that my two year old had been crazy when she visited.
She came up on my social media and it strangely brought a lot of that annoyance up to the fore, which is of course unreasonable. But was I reasonable to be upset at the time? I found it very hurtful to welcome someone into my home and for them to run my child who was struggling down to everyone at the table.
Would you have found this hurtful? And yes I know it was in the past etc etc but just curious.
