It's definitely true what they say. Parenting, in some ways, is easier the second time around. Now I have the retrospective wisdom that the timing of potty training is not about me or whether I'm a good parent, but only about my child and his own readiness. Poor Isaac had to suffer before I could gain this precious parenting gem.
Lincoln has responded well to the 3-Day Potty Training method (let me know if you want a copy of the ebook) and of all the methods I've read about it seems like one of the best. You have to be extremely consistent and vigilant through the 3-day period and you need the guts to go cold turkey into undies (we threw out all the diapers--even at night--but he almost always stayed dry). But it has saved a lot of grief for all of us!
