Dear mumof5,
The age of sacraments in Melbourne can change from parish to parish and is at the discretion of the priest. Baptism of course shortly after birth, Sacrament of Penance in grade 2 or 3 and Holy Communion in grade 3 or 5 and Confirmation in grade 6. Are you moving to Melbourne. I know of some great parishes, one with perpetual adoration.
God Bless
