My dsis says that my nephew (now 7 and speaking fine) did this around this time (she's not sure when exactly) because of the rush to get words out before brain engaged IYKWIM. I don't know whether to see my HV and get the ball rolling to see a SALT, or to just wait and see.
We have no experience of actual stutters in real life so not sure if this is one, or just another phase of speech. Anyone else had this???
