Huwag po itolerate ang pangangagat. Basta kapag nasasaktan kayo, iunlatch nyo agad sya (insert a clean finger sa pisngi ni baby to break the suction), then calmly say "no biting". Huwag sigawan or magreact in an animated way, which they might find amusing and make them do it intentionally. Soon enough, matutunan rin ni baby that whatever it is he's doing is wrong and will result to "no more dede" kaya titigilan na nya eventually ☺️
