I don't know who ever started the myth that girls were easier, but my daughter was a struggle and finally we managed to get her there a few months after her 3rd birthday. My son was eager at 2 and for a few months would sit there, but now at 28 months he is in the NO stage for everything. I would wait a few months and find a time when you can hunker down together in the house. I am going to try over Christmas vacation. If all else fails, I know he wants to go in the big pool this year, which requires potty training and is a big incentive. Good luck.
