If you have a two, three or four year old you know, no speech, no social interaction, I can't emphasize enough: Don't wait, you need at least 20 hours a week of one-to-one teaching.
Daca aveti un copil de doi, trei sau patru ani stiti, care nu vorbeste, care nu interactioneaza social, nu pot sublinia cu destula tarie nu asteptati, aveti nevoie de minim 20 de ore saptamanal de antrenament unu-la-unu.
