Unfortunately, our daughter was 3 months old when I bought the book. Better it would have been to buy it during pregnancy, as we now advise or estimate had some information (z. B. When the first movements were felt in the abdomen.).
Even now (six months later) I already like leaves in the book.
A very nice idea to sign up later to remember the baby time and certainly interesting for the children in 20 or 30 years to compare the development of with our grandchildren :-)
