When I started to research my family tree 20 years ago, many genealogists advised me of the need to have an open mind and to always expect the unexpected. People are human. They're not robots. In all likelihood, there weren't any computers in the hospitals. There are many records in my family tree that don't make sense, chronologically. Obama's birth record does not fit into the category of irrational.  The sequencing of the registrar's number is only off by 3 to 4 and that is only taking into consideration, the Nordyke twins, whom we're aware of, with birth dates of her children that are close to BHO, who is the only mother to have come forward so far. Easily, 3 to 4 other births could have occurred between 8/4 and 8/8 of 1961 and I'd bet my bottom dollar there are others that are out of sequence by a few days from the same hospital(s), both before and after the birth of BHO and the Nordyke twins in Hawaii, in 1961. Hope you can sleep. I'd be more concerned about Skittles jokes ;-)
