Pusod ni baby

I watched some birth classes and all the doctors there said to not put anything on our babies umbilical cord, just let it dry. As per my pedia naman she said use a cotton balls with small amount of 70% alcohol to clean the surrounding area 3 times a day. Pero ako ang ginawa ko, super rare Lang na gumamit ako ng cotton with alcohol, hinayaan ko Lang matuyo at natanggal na after 1week.
