My dd is going to her first birthday party this afternoon for a boy in her nursery. She's four. It's at a soft play do kids tend to wear party dresses when they're doing something physical like that? Or do you send them in something more comfy / practical like leggings and top? I know it's daft to worry about this but I don't want her to be the odd one. She's has a learning disability and some physical disabilities so I already feel like she's the odd one out enough already. Advice of the mumsnet hive mind appreciated.
