Is she still ahead of her peers at school? If so, get her tested now in case this changes due to behavioural issues.
My daughter was also very ahead cognitively (alphabet at 16 months; add, subtract, multiply, read and write full sentences all at 3 yrs, etc), and she's never been tested. She's 9 now, and I KNOW that she is gifted, but she also has extreme anxiety that interferes with her output (so I suppose she'd be 2e). Our pediatrician advises against testing at this point because the anxiety would render the results inaccurate.
Bottom line, I SO wish I had had her tested when she was younger. I've had to fight to get her enrichment at school because she has no testing to back up my "claims" that she is gifted(arrgh). Math is the only subject in which her marks reflect her ability - likely because it is precise and suits her perfectionism, and it's not personal like writing.
Anyway, I say get your daughter tested if she is still ahead of her peers - you never know what the future will bring in terms of her behavioural development. I wish I had my daughter tested before her anxiety started to interfere: this happened after preschool, when she realized that other kids her age didn't read and write - that was the end of her output matching her ability
Anyway, good luck!
