As most have recommended to start at 1/2 pace, I would say the same.

I did LHFHG with older ds right after he turned 5. I did not know about doing the guides 1/2 pace

He did great, but I was glad that we found out about doing guides 1/2 pace before starting Bigger! With my 2nd ds I started him at 5 1/2 and we go half pace so we do not get to Bigger too soon! He is loving doing LHFHG and I am loving teaching it 2nd time around.
Success with your decision and with all advise, the Lord will show what is best for your little girl, who looking at your blog, seems to have the true firstborn eager to learn attitude. She is just adorable
