I haven't heard of that book, Mya, but it sounds like it would be good! People have been parenting since before we had books... You have instinct and that is better than any book out there. I like the "technical" parts of the books like "Your baby is the size of an avocado now" and "your baby should be able to hear you now". Every pregnancy is different and every baby is different.
I've really learnt to trust my instincts (without influence from others). I do feel its important to be educated when making decisions. I don't tend to blindly trust others (doctors, family, society), I make sure I am armed with all the facts and research before making parenting choices (eating, sleeping, care, discipline, medical issues). I really make sure the decisions I make are about me and my baby and not about anything else. I think reading up (from yhe RIGHT sources) is quite important as then you make whatever decision and you can be confident you did what youre comfortable with. When you know better you do better.
