It’s a very helpful book. Of course, you only start reading these helpful books (in most cases) when you already have issues, not as a preventative measure. I read the newest edition, so there is updated information which was great. It made me realise all the things that do work for us and which don’t.
The reason why it is 4 and not 5 stars (and that’s very personal to me), this book was not written for Europe. Some of the dangers discussed, are not a thing in the EU. Same with the ivf procedure, so I could relate a little bit less to this.
