They do if they are going to follow the instructions of Acts 2:38 [And Peter said to them, "Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.]. I was not the one that claimed that children should obey Acts 2:38 as children … you implied it with the quote “Acts 2:38-39 says children”. I merely pointed out that if children are going to obey Acts 2:38, then they need to follow ALL of the words and not just the word “children” plucked from the verse while ignoring everything else the Holy Spirit inspired to be written.
