There is a reason why the Catholic Church conducts baptism nga baby pa lang ang tawo and its precisely bec of that.
As per Wiki :
Infant baptism - Wikipedia, the free encyclopedia
The instruction then gave guidelines for pastoral practice, based on two principles. The major principle is that baptism, as the sign and means of God's love that precedes any action on our part and that frees from original sin and communicates divine life, must not be delayed. The subordinate principle is that assurances must be given that the gift thus granted can grow by authentic education in the faith and Christian life. If these assurances are not really serious, there can be grounds for delaying baptism. If they are certainly absent, the sacrament should even be refused.
