Matryoshka, our experience of speech therapy has been the therapist saying 'hey let's play!' And they play games together so the speechie can gauge where bub is at. They will try to engineer situations where bub has to talk. They'll ask you a bit where bub is at too, what they say and what they struggle with. And then you'll get homework, ideas on how to encourage bub to talk, similarly to how they do, through play and things. Like, ours suggested putting their favourite toy in a clear tupperware container (or other container that they can't open) so that they're forced to use words to ask for it. Or modelling behaviour for them, perhaps with family friends, so they can see what they're supposed to to, and then giving them a turn. Or playing games where they need to talk, or sabotaging their play (like stealing something they need so they have to ask for it).
