That is incorrect. It is an exorcism ritual that dedicates the child to God.
If you are going to talk about practices outside of your own church at least get the facts right.
Something to
consider:

- to change one's mind for better, heartily to amend with abhorrence of one's past sins
Acts 2:38
[38] Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Question: Does Acts 2:38 prove that you have to be sorry for your sins and turn from them in order to be saved?
Answer: No. Peter was speaking to the Jews about their rejection of Jesus. They had been complicit in His crucifixion, which could not be undone.
So, in this case, there is no sin to turn from. They simply needed to repent (change their minds) about who Christ is (God) and what He did for them (paid the full price for their sins). And, being baptized for the remission of sins means that once they believe, they should be baptized, not in order to become saved, but as a testimony of their belief.
