Did anything significant happen during his birth? Any astronomical coincidences? Any wise men come to visit? Was anyone other then the Bab and his followers expecting him? Any proof of this? This is a sincere question.
The Bab wasn't there. The Bab was two years younger than Baha`u'llah. (The Bab was born in 1819, Baha`u'llah in 1817. This does match a Shi'ih prophecy of the Mihdi saying "I am two years younger than my Master.)
Hand of the Cause, William Sears wrote two books about the mystic and historical aspects of the advent of the Bab and Baha`u'llah and both discuss the comets of 1843 and 1846:
"This appearance is reported in Our First Century as follows: 'The
Comet of 1843 is regarded as perhaps the most marvelous of the
present age, having been observed in the daytime even before it was
visible at night -- passing very near the sun, exhibiting an enormous
length of tail; and arousing interest in the public mind as
universal and deep as it is was unprecedented.'
The New York Tribune, and the American Journal of Science devoted
special sections to this great comet of 1843, the Journal of
Science identifying i in those very words: 'The Great Comet of
1843.'
I found an even more dramatic story told in the heavens during
this same period. It was the story of still another comet. It was
seen in the skies in 1845. It appeared to be quite an ordinary
comet in a year in which some 300 comets had appeared. It had been
studied many times in the past. In 1846, the comet was still
visible.
However, at this period in its history, it became one of the rare
comets of history. It was now entering what were to be the last
dramatic moments of its life. It was called Biela's comet, after
the original discoverer. The Encyclopedia Americana (1944 ed.)
gives the following account of this event: 'It was found again late
in November 1845, and in the following month an observation was
made of one of the most remarkable phenomena in astronomical
records, the division of the comet. It put forth no tail while this
alteration was going on. Professor Challis, using the
Northumberland telescope at Cambridge, on January 15th, 1846, was
inclined to distrust his eyes or his glass when he beheld two
comets where but one had been before. He would call it, he said,
a binary (twin) comet if such a thing had ever been heard of
before. His observations were soon verified, however.'
Sir James Jeans has written of this same comet, saying: 'The most
interesting story is that of Biela's comet which broke in two while
under observation in 1846.' [Through Space and Time, Sir James
Jeans, 1934, p. 154.]
Professor Challis was wrong. It was not the only binary comet
in history, just as Sirius was not the only double-star, nor the
Star of Bethlehem the only bright star, or novae, or conjunction
of planets in astronomical history. It was not the uniqueness of
the event that made it important in prophecy, but its remarkable
timing.
Biela's comet disappeared in 1846. It returned in August, 1852.
This was the very month and year in which Bahá'u'lláh was cast into
an underground prison in Teheran. It was the beginning of the
forty years of his Mission which ended in Israel in 1892 with his
death; the forty years foretold by Micah during which God would
show to the Messiah 'wonderful things'.
The year 1852 was also the beginning of the year 1269 of the
Persian calendar. It was the ninth year following the Báb's
prophecy concerning the coming of Bahá'u'lláh. The Báb had
written,
'In the year nine ye will attain unto all good...in the year nine
ye shall attain unto the presence of God.' [Epistle to the Son of
the Wolf, p. 141.]
When the single comet which had now become a twin comet
reappeared in August 1852, one half had receded far into the
background. The other half now dominated the sky. So the Báb, the
Herald of Bahá'u'lláh, had now passed into history through
martyrdom, and the one whose coming he had foretold, Bahá'u'lláh,
had now assumed his Mission.
An account of the reappearance of the comet states: 'Late in
August 1852, the larger came into view and three weeks later the
smaller one, now much fainter than its former companion.'
[Encyclopedia Americana,1944 ed., Vol. iii, p. 690.]
Sir James Jeans confirms this, saying that in 1852, the two
pieces were one and a half million miles apart.
Bahá'u'lláh has written of that hour when the twin-comets rode
the skies. He laid chained in an underground prison. Of that
moment, he has said:
'lo, the breezes of the All-Glorious (God) were wafted over Me,
and taught Me the knowledge of all that hath been. This thing is
not from Me, but from One Who is Almighty and All-Knowing. And He
bade Me lift up My voice between earth and heaven....' [God Passes
By, p. 102.]"

Take it for what you will.
As to remarkable childhoods, the early years of both are discussed in some detail in Dawnbreakers.
