I get mine to pause, think about what they want to say and then start again. My son still does it sometimes and he's 5, but it's a phase my eldest 2 both had.
Mine stuttered for like a week then just never did it again. That was about 3/4 months ago
Yes my son does exactly the same. Some days are worse than others and I find it’s when he’s excited or really wants to say something. I mentioned it to health visitor and she said it’s normal but has referred us to speech therapy to make sure it doesn’t become a problem x
Slow down speaking to him. My kid tongue tied I just slow my sentences and break the words down to him. Consistently. He’s improving a lot.
