The Wonder Weeks Milestone Guide

There’s nothing better than becoming parents. You are a team, a great unity. You want to do everything right, which brings, no doubt, a whole bunch of worries and questions with it. The questions and doubts are perfectly normal. They are even good to have. They bring out the best in you, and this is to your baby’s advantage.
Over the years, parents have asked me lots of questions on all kinds of subjects. They are questions that are not only on these parents’ minds but that are interesting to every father and mother. In our new book ’The Wonder Weeks Milestone Guide’ I answer all these questions and more. Happy reading!
