My son (3, 5) stammers on vowels. For example,
A-a-a-where? U-u-u-whom? When it or him you ask to repeat the same silently, he speaks normally.
Why? How with it or this to struggle? In advance thanks for the answer.

Urgently address to the psychoneurologist, t. To. It is necessary to establish or install the exact diagnosis. Perhaps, what is it not a stammering, t. To. During this period phrase speech is formed. But if the diagnosis will prove to be true, it is necessary complex korrektsionno-medicamental influence (from the neuropathologist or the psychoneurologist - medicinal preparations, from the logopedist - correction of speech).
