Read, READ, REAd!!!
We've read Dr. Sears books and Babywise. We've implemented some of both. My husband read and loved Babywise and helped us implement it from the moment our son was born. It was simply fantastic for us.
I'd like to respond to this quote below left by another mommy.
"The Babywise books seem to be recommended by many, but please know that during the early months of breastfeeding that this method can cause issues with milk supply. The American Academy of Pediatrics, as well as Dr. Dobson, have some against some of these methods as potentially harmful."
Read the book from cover to cover. Have your husband read it too. Don't be legalistic! Let the method work for you. Don't be a slave to it. From what I have read those who had issues with milk supply or harmful situations were excessive and rigid.
Using this method made my milk supply plentiful! I could've fed the nation of Africa! Ha Ha
After observing friends and their families over the years, I found that the families I most wanted to model were the ones who used Babywise / Growing Kids God's Way.
Another good recommendation for the toddler years and beyond is Sheperding a Child's Heart.
Just read a lot and do what seems most appropriate for you and your family. Definitely get your husband in on the decision. His support and participation will make all the difference.
Congratulations! You will LOVE being a mommy!!!
