When my daughter was one, I met a mum with a daughter the same age. Both our girls were pretty verbal kids, so they got along famously. The mum was very enthusiastic about how advanced her daughter was, she clearly loved her kid, and told me that her daughter had walked soooooo early... 10 months! DD walked at 10 months too, but I just smiled and said, "Wow you must have been excited!"
She was a single mum who was pretty isolated socially from other mums. I guess I could have taken her as ultra competitive, she said the word "advanced" to describe her daughter about 50 times, but I honestly think she was just lonely and had nobody to talk to about all this stuff. And for all I know, her daughter WAS advanced. She didn't seem it, tbh she seemed pretty on par with my DD, but hey, I am no professional! She wasn't b!tchy about it though, she just seemed genuinely in love with her little girl.
