DD1 is 3.10yo, very bright and articulate. 3 weeks ago she started pronouncing words oddly - words she could previously pronounce without any difficulty. Traffic has become ter-affic, cross has become ker-oss, tree is ter-ee, clock is ker-lock, bravely is ber-avely etc etc. I thought it was a conscious thing, a bit of a phase that she would get fed up with after a few days but 3 weeks on she is still doing it. It seems to be words with l or r as the second letter.
I've ignored it most of the time so as not to make an issue of it. Once or twice I asked her to pronounce a word normally (gently, I didn't make a massive thing of it) and she paused, then pronounce it correctly. But then carried on with the weird pronouncing thing. Is she exploring how words are spelt and breaking them up consciously? Anyone else had this experience?
