DS 2.5 was relatively late to start talking properly, didn't really get going until after 2 (though understanding has always been good). Even though his spoken language is pretty good now he always seems like he has to think hard about his words and work to get them out. Recently I've started to notice him stuttering, especially when tired and on certain sounds like t. He's also even more recently started to put his hand in front of his mouth when he's doing it, which makes me think it might be more than a normal developmental dysfluency. Obviously I'll seek advice from the HV but does anyone have experience of a stutter developing this early?
