This is what I'm taking about with my ILs, kasi 1yo pa lang mga anak ko pinapalo ko (sa kamay lang as a punishment for doing something wrong but I make sure to explain their fault). Sabi nila wala pa raw isip ang mga bata. NOT TRUE. This is time that they test your tolerance kaya maliit pa lang dapat malaman nila ang tama at Mali. I don't tell them the "BAD" word kasi hindi naman talaga sila ang bad, kundi yung ginawa nila. Pag lagi niyo sinasabing MATIGAS ULO MO, MAKULIT KA, BAD KA...they will tend to be like that kasi ganun ang tingin nyo sa kanila,
Siguro at this time...wala na sigurong sigawan, bangayan, atbp. Ang kelangan ngayon is to completely understand the situation and reverse psychology. Tayo ang iintindi at tatahimik. Try these maybe it will work for you.
