My 3 year old son being zoning out at school and sometimes at home he had a eeg done but can back normal. What s the reason why he does this? And also been having other problems since he was baby he cries a lot for no reason he s so sensitive to everything like he won t brush is teeth he won t wear tags on clothes he doesn t like hair cuts and he gets mad really easily because it wasn t dark outside or i didn t answer right away there s more to much to write.
