The evidence that suggests this is as follows:


 * We know that Emma was 17 when she conceived Henry, and 18 when she gave birth to him, and that both his conception and birth occurred in the same year: 2001.


 * By his own admission, Henry is 10 when he comes to find her in Boston on October 23rd, 2011.

My dear, if Henry was, as you say, born in October of 2001, and it is early 2013, he would be eleven at this point in Storybrooke's time, not 12.
 * Even accounting for the 1-year time jump in the middle of Season 3, the show's internal chronology has only reached the early part of 2013 by the beginning of Season 4, meaning that Emma is 29-going-on-30 and Henry is 12-going-on-13.

The only way for him to be 12, which is his age, in early 2013 is for his birthday to have already passed.
