My 26 month old DS can..
speak in 3/4 occasionally more word sentences, lots and lots and lots more single words although not well understood but people not close to him.
decent understanding and can follow instructions well.
uses pronouns like me, I, mine.
can run
jump with both feet off the ground, although this is very new in the past few weeks.
uses cutlery (messily) but also his hands to eat a lot.
can do 5 piece jigsaws with minimal help.
points at things he sees (aeroplanes, trucks etc) and for things he wants, although this is reducing as his speech improves which I think is fairly normal.
can ride a balance bike, although still not brilliant.
this is just off the top of my head but I think he’s fairly average and on track with his development and I have no concerns.
