@AladdinMum are you a speech therapist? I lurk on a lot of posts and don't usually post myself but I've seen you.
@Wellybobs2
I've just been to a NHS speech therapist run speech workshop. I'm a parent of a toddler with a speech delay too. They said children with a speech delay often suffer from poor attention, like at preschool they would move around the tables and activities quickly only engaging for a few minutes. So I would say, they should be able to engage for longer than a minute even at 2 yrs ?!
The workshop I've just been to suggested taking turn games, for building attention span. Can be as simple as mummy's turn -puts piece into puzzle, DCs turn- puts piece into puzzle. Can be any game or fishing / hook a duck / roll the ball back and forth etc.
They spoke about if your child loves playing cars, add in some people figures to build more speech opportunities into the game and to make it last longer.. so ..
Drive to shops, ice cream van, car needing repair at the garage. Or playing House type dolls games or tea parties, shops. They said if you have a boy, you can use Dinosaurs or Peppa pig toys instead of dolls whatever gets them interested.
Play at their level and you try to speak more when playing with your DC or you can do a commentary on what they are doing. Repeat the same single words a lot in context.
The therapist said words together come once they have about 50 single words. Item words like shoe are the first to come, but also people names. Then you might get the two words together like Mummy Shoe.
I would try to self refer for a speech assessment. You might be able to google to find how for your area or phone your HV team and ask how to self refer. Some areas even have speech drop in clinics and they can tell you the info.
The NHS will probably not offer any actual speech therapy pre 3 years unless other issues, but you are in the system if you still need to be. You might get offered a workshop like I did or a group course. Anything helps in my opinion and hopefully your DC will come on leaps. Good luck
