I take ds to a class for 0 to 4 year old music etc. He's one of the oldest but still likes going. He's not shy! Anyway today one of the nans brought her 2.5 year old granddaughter. She said she hasn't been for a while as alot of the bigger kids are boisterous and her granddaughter was scared because she's shy. My DS is one of the oldest so I did feel it was aimed at me/us. I didn't respond tbh.
The class is aimed at both their ages so they obviously both have a right to be there but it was a bit uncomfortable
