AITA for letting my daughter still sleep with a teddy bear?

My daughter (8) still sleeps with a teddy bear her grandmother gave her when she was 3, she's always been shy and timid and gets easily frightened, so at night she's inseparable from her bear.

I (34F) have been told by a few of my extended family members at a family reunion last week that she's too old to be sleeping with a stuffed bear afterthey saw her sleeping with it in her grandmothers living room. (which is especially ironic coming from my brother who slept with a Batman plush until he was 11)

Personally I don't see a problem with it because it doesn't affect anyone else, and it makes her feel safe and comfortable at night.

So Am I The Asshole?
