3yo and early milestones?

[Naicecuppatea]

My Dd2 (3 last month) has been quite quick with most of her milestones and I feel awkward writing this even. She toilet trained herself at 18 months, because her big sister was doing it. She seems pretty good at reasoning and her vocabulary is excellent, on a level with her 4.5yo sister, who she regularly leads games with.

She started writing her name a couple of months ago, and now she is correctly sounding out using phonics and reading most 3 letter consonant vowel consonant words (again from absorbing what her sister is doing, nothing that we have done with her). Recognises all her numbers to 20. Just has trouble writing and forming some letters, but she definitely tries to write words.

Just wondering if this is particularly out of the ordinary for a just turned 3yo, or is it usual for most siblings?

Meant to add she crawled at 6 months and walked at 9 mo, was hardly a baby at all really!

I would say that's quite advanced. My DS is 3.1 and still has problems with speech. Can't say 'ss' sounds amongst others. He can recognise his name in written form but I don't think he can read digits or letters in isolation. What a pleasure it must be for you! I guess what you might focus on is advice and ways of challenging her so that you can bring her on a bit more.
