I see more support by inference for infant baptism than I do for infant dedications in the NT. But I have never see either side say the ceremony was un-Biblical.
"The idea of dedicating a child to the Lord can certainly be found in the Bible. Hannah was a barren wife who promised to dedicate her child to God if He would give her a son (1 Samuel 1:11). Luke 2:22 begins the account of Mary and Joseph taking Jesus to the temple after forty days in order to dedicate Him to the Lord. This was slightly more involved since it involved a sacrifice, but once again this ceremony did not indicate any level of salvation.https://www.gotquestions.org/baby-dedication.html
There are no examples of baptizing infants in the NT.
There are no commands to baptize infants in the NT - which is strange, if it saves.
