My son I have only recently noticed (to my shame) is mis-pronouncing his words.
TH words he uses an F - so think becomes Fink, thought becomes fought and so on.
The other times this happens is with D's and T's occasionally.
I have no idea when this started, but expect it was early on.
We talked about correcting this together, through practice and reminders but this doesn't seem to be having any impact.
The school he attends (state school in the US, we are Brits) does have a speech therapist on site who I could ask for help.
Does anyone have experience of this and any advice to give?
Thanks.
