I don't think you're crazy - I've frogged things because I wasn't happy about how it turned out... I just waited until I wanted to use the yarn again to ease the pain of ripping out something I just worked so hard on:roll:
That being said, I would definitely block it - you can always tear it out after that if it still doesn't look right.
Also, how does your daughter like it? I think we're often more critical of our own work than is necessary - you might not like the pattern, yarn, or just the frustrating experience, and that might be shading how you're seeing the finished product.
And if you do tear it out, have a cry, then be happy it's all over;) Maybe you can try one of these patterns
And there are a ton here - you should be able to find something!
