"Hi there, just wanted to drop you a quick line and say THANK YOU for all the invaluable advice you gave us. Your new method worked like a charm for our little Leon and we don't need any diapers anymore. 100% recommendation for your amazing guide!! - Sarah"
"Our Sophie just turned 2 when we started with your potty training. It was pretty similar to what you described in your book and we had to fight HARD against her stubbornness. But somehow after time she finally "got it" and it took just a little bit under a week for Sophie to become potty training. Thank you!!"
"We are just in day 2 of your potty training plan, but I can already see MASSIVE progress... My daughter is not completely out of diapers yet, but with this level of progress it should be any day now. Congratulations on your amazing guide and thank you. Best, Kathrin"
