Could It Be a Stutter?

I'd say-- see if this lasts before talking to a specialist. If it has happened all of a sudden and only at consonant ends, it sounds to me like the teacher is over-emphasizing that part of the speech. So it could very well be a novelty. Plus, some kids go through short phases where their brain and mouth, as it were, are a little disconnected, so they'll hesitantly start a sentence with two or three words and repeat those until the whole thought/sentence 'gets there'.

And if you are asking him about it or commenting on it (even within his hearing) it will give the repeating of those consonant sounds more attention and make them MORE interesting to him. I haven't ever seen a true stutter just start suddenly... I'd talk to the teacher and ask to observe when she is teaching-- she may not even know she's over-emphasizing these sounds.

If they are teaching him a language which emphasizes the double consonant sounds of certain words, I'd say that it is likely imitative.

No, not a stutter. He's playing with his language skills. Not intentionally. He also could possibly be doing something similiar to adults saying "uhhhh" when searching for a word. Sometimes kids can't think quite fast enough to say what they want to say. One time my older son was having a conversation with his dad, and stopped and looked quizically at my husband and said "I don't have enough words." He was 3.

I would not do ANYTHING right now with him. Don't fuss at him or give him attention for it. Let this go for several months. If he is still doing it by the time he's 3 1/2 or 4 (depending on how old he is now) or if it gets worse, ask the ped for an evaluation with a speech therapist. Believe me, I am a big proponent for speech help, but I don't think that this is warranted right now. More than that, I don't think you should show him attention for it.

Sounds like he's having fun with the sounds coming out of his mouth. Or maybe he's imitating someone who he thinks sounds cool. Stuttering is usually at the beginning of the word / sentence.

We moms look for stuff to worry about with our kids don't we?

It's a phase most kids go through. Totally normal. Ignore it and it should go away.

Maybe.
Maybe not.
Does anyone else in your family stutter?
Stuttering is fairly common between 2 1/2 to 4 yrs old but most grow out of it.

My son went through this phase around this age. He outgrew it. His was the beginning sound, though.

They MAY be working on phonics and the beginning and ending sound in a preschool class. I would ask his teacher.

I just ignored it. All that I read was that telling him to slow down wouldn't do any good. Like I said, he outgrew it.

Probably not, especially since he's only doing it in one language and only with certain sounds. K and T are very hard-sounding endings that you can really put emphasis on, so it's easy and fun for kids to exaggerate it. Are there comparable words in your other language that he isn't doing it on? Or are those sounds less prevalent?

I wouldn't worry at this point. If it persists for several months, then I would do something about it.

Kids do go through stages with language where they need to be gently guided in order to speak properly. Don't obsess over it, just gently repeat what he says back to him correctly and ask him to say it again. "In the bathroom sink, not, 'sink k k k k.' Now you try."

It does sound like he may be mimicking a teaching technique. If they're learning letter sounds and sight words, this may be something he's hearing at preschool. Again, it's not anything to worry about. Gentle correction will fix it.
