Congratulations Mike!
I have a daughter who just turned 3. She's been hell on a trike for a year now. For her 3rd b-day we bought her a specialized kids bike with training wheels. All she cared about was that it was purple!
She really struggled with it the 1st few times we put her on it because of the coaster brake. She had developed a habit of getting herself rolling by rocking backward a bit before rolling forward (like a truck stuck in mud), and it caused her to freak out in the first 2 seconds on the bike and jump off. Last Saturday after my club ride, my wife and I talked to her about patience and that we would work with her as long as she would work at getting the "big girl bike" rolling. We took turns rolling her feet in circles and explaining to keep pushing forward and after less than 5 minutes, she rode 100 feet all by herself!!! Needless to say, I was jumping up and down and acting like an idiot.
All that to say, it's amazing having a daughter and I wish you and your family a wonderful experience, happiness, and health!
