Yes quite true. The answer is simple.
But bednobs's original question raised a number of points beyond the simple answer. As well as this the later comment (about the odds of the next child being anything other than 50:50 as a result of the "two in a row" complication) warranted further explanation. Very often I believe simply supplying the correct answer alone is not very helpful. Hopefully the explanations provided by various people which were provided as the discussion widened has helped bednobs understand the reasoning which leads to the answer.
