DD is 16 months old. Today she picked up her alphabet peg puzzle and put 10 of the letter pegs into the correct letter spaces. Underneath are pictures are things starting with that letter.
I don't know if this is advanced or not. Probably not! Although I was pretty impressed with her because she has been behind her peers on every single thing! Walking, talking and all that. Although she's kept up roughly with what the NHS book says so Im happy 
Anyway, my question is HOW did she do this? I mean what skill has she used. Maybe she recognised the shapes of the pegs, or the order of the letters or something. I just want to know so I can do other activities that bring this into play because it seems a waste not to encourage her. Perhaps someone who works with kids will know.
The pictures underneath are things she doesn't even know like giraffe and ice cream so I don't think shes recognised them from another toy.
