My 7yo just read an entire book to me without asking

I wasn't even expecting it. We were sitting on the couch and Emma just grabbed one of her chapter books and was like "Dad can I read this to you?" She got through the whole thing, maybe 30 pages, and only asked me about like 3 words. Her teacher mentioned last month she was struggling with fluency but I guess something just clicked. My wife thinks I should tell her teacher but honestly I'm just gonna let her feel proud of herself first. Anyone else have that moment where your kid just... levels up?
