Longer answer: yes, but only if the one single examiner handling this patent at the time had known of you, known how to contact you, and been able to obtain any information from you (and mind you, he/she likely could not have told you why he/she wanted the information).
The other problem is that while you did this over twenty years ago along with the others on the playground, where did any one of you publish anything describing your alternate swing method? Because to make a rejection stick, the patent examiner has to find some publication by you or one of your playground mates from twenty years ago disclosing to the public your new swinging method. This is because the position of the courts is that an applicant deserves a patent __unless__ the us patent office can prove otherwise (and "prove" pretty much means "prove to the level of a civil trial in court").
If the system were reversed, i.e. that applicant did not deserve a patent unless they (the applicant) could prove it was sufficiently new to deserve a patent, there would be far less of these "swinging on a swing" type patents.
