Sounds like you're having fun with your daughter's hobby, which is a good thing!

I would say... keep with what you're doing.

As your daughter gets older, maybe some am dram groups (in summers you can usually find ones that run for a week or two just for children and a play at the end), maybe music lessons if she wants to do that, lots of time for just having fun with it too.

Also, encourage other interests your daughter has, even if she has less talent. I have no talent for singing but enjoy it - it was quashed a lot as I was growing up (save 2 nights a week with some chums) so I'm very self-concious about it now, but DS doesn't care! I am better at quadratic equations than I am football... but that doesn't stop me kicking a ball around in the park. It's great not to have to work for your hobby, but even better to see yourself improve at something with a bit of effort IMO.
