Regarding oil before or after bath, hindi na po siya inppractice ngayon. Powder, delay mo muna, pwede mo naman hindi lagyan kasi mabango naman si baby lalo na yan NB pa and developing pa ang immune system niya. Also baby's skin is sensitive and prone to irritation. Lotion, 4mos ako nagstart, pang-massage ng mga extremities niya.
I never used oil bago maligo si baby kasi hindi naman nahugugasan ang oil so kakapit lang ang dumi. No powder and lotion (kung hindi naman dry ang skin) until 1 year old as per my baby's pedia.
