Im my opinion no one younger than Jesus was at the time of his baptism, should be baptized. the WT always criticized child baptism, in the past, so when i heard of several very young grade school children getting baptized, I was sickened.
questions from the reader with a reference to a 1964 watchtower for further reading.

Under what circumstances might rebaptism be considered?
Under certain circumstances, a baptized person may want to give thought to the validity of his baptism and may consider rebaptism. At the time of baptism,
for instance, an individual may secretly have been living in a
situation or engaging in a practice that could have resulted in his
being disfellowshipped if he had already been validly baptized. Could he
make a dedication to God in such circumstances? Such an individual
would have been in a position to make a valid dedication to Jehovah only
if the unscriptural conduct had been discontinued. Therefore, a person
baptized while such a serious impediment existed may appropriately
consider the necessity of rebaptism.
What about an individual who was not practicing sin at the time of his baptism
but whose subsequent wrongdoing required the formation of a judicial
committee? Suppose he then claimed that he did not fully understand what
he was doing at the time of his baptism and said that his baptism was not truly a valid one. When meeting with a wrongdoer, the elders should not raise questions about his baptism and ask whether he feels that his dedication and baptism were valid. After all, he heard a Scriptural discourse about the significance of baptism. He answered affirmatively questions regarding dedication and baptism.
Then he changed his clothing and was physically immersed in water. It
is, therefore, reasonable to believe that he fully understood the
seriousness of what he was doing. The elders would thus treat him as a
baptized person.
If the individual raises the issue of the validity of his baptism, the elders may direct his attention to The Watchtower of
March 1, 1960, pages 159 and 160, and February 15, 1964, pages 123 to
126, where the matter of rebaptism is discussed in detail. Eventual
rebaptism under certain circumstances (such as a lack of sufficient
Bible understanding when one was baptized) is a personal matter.
