Those who have reached the age of reason that have not been baptized need to repent and be baptized. Those that have been baptized as infants need only repent. Jesus was not speaking to infants who obviously have no need to repent nor the ability to.
Oh, I get it; you are interpreting that verse as one action; well, I interpret it as two: repent, be baptized. Where does Jesus say you have to do them together?
I'm not interpreting anything...And the scripture tells you not to interpret...
Neither Jesus nor anyone else says you must repent and get baptized together...What Jesus and the apostles say is that you must repent...Repent before baptism...Even repent without baptism...
There's not a single case of getting baptized before repentance or without repentance...
= No baptism for babies...It won't hurt 'em but they'll just get wet and cry...
