Is there any implication in the Bible that Jesus will come again as an
infant? I was always led to believe that the 2nd coming of Christ would be
on a cloud.

No, there is absolutely not a shred of evidence to cause us to believe
that Jesus will come back again as an infant. There is also no conceivable
reason why this would be so. Whether one should say that he will be on a
cloud is questionable also. The Bible describes him coming “in the clouds”
which should be taken as descriptive, symbolic language which could be
understood to mean that his return will be visible or perhaps even
literally visible in the sky. “In the clouds” is a figure of speech, not
to be taken literally. The passages which describe the return of Jesus are
apocalyptic, which means that they are written in a highly symbolic style.
Anyone who claims he or she knows exactly what the return of Jesus will be
like is deceived. However, one thing we can say with great confidence is
that it will be with great power. Jesus will not come back as an infant.
