My daughter got to know that "頭" has four ways of pronunciation, depends on what letter comes after or before that.
頭(zu)痛 三頭(tou) お頭(kashira) 頭(atama)
She was confused and asked me how I distinguish the pronunciations. I said that we just remember by saying and writing many times. She was surprised and said "It's hard for me". No worries. You have plenty of time to get used to it.
