when to celebrate 6months birthday for a baby? Is it at entering into 6th month or when entering into 7th month .... actually what people will tell is when baby entering into 6th month they tell 5 months old

A. Hi you can celebrate sixth month birthday after six months completion. when baby completes six months. For example when the baby born you will say baby has completed one month as once the baby completes after one month. So six month celebration is celebrated on six month completion date.
