My little boy has over night developed a stutter. He will be 3 mid April. His speech has developed as usual throughout. How ever he's always developed in block and suddenly. For example there was no sign of him walking then one day he took 4 steps, same with rolling over he suddenly rolled everywhere, his speech was limited then all of a sudden he came out with 30 plus words. I have read that stuttering can be common but do I need to worry yet? Any advice please or someone who has been in a similar situation. Thank you in advance.
