Model the behaviour you want your child to learn. Mahirap e undo pgnatuto na ang bata. Kahit ako sis may time talaga na ma raise yung voice ko, di naman sigaw.. i think shes not used na pgtaasan ko sya ng boses. my toddler will scream and naku simula na ng tantrums. If I calm down, so will she. I tried to be consistent and undo bad habits.. mahirap talaga but i just have to be consistent. this is an ultimate test of patience.
