I have a boy turning 4 next month, napansin lang namin, pag di niya nakukuha agad yung gusto niya nagsasabi siya ng "ok, I don't need/want it anymore" "i will never have it". We try to encourage him the value of waiting, minsan kasi may ginagawa pa kaya di maibigay (if he wants milk or bread). how do ou address this kind of situation?
