I wanted to comment to Judy on here. I am glad nursing your children worked so well for you. It is not "natural" or easy for ALL babies and mothers. I am guessing none of your chilren were low birthweight or premature? That makes a huge difference when it comes to the ease of breastfeeding. I gave birth to twin boys who were premature and one was low birthweight. Premature babies have trouble latching on and are not as hungry as full term babies and it is no easy feat trying to make a baby eat when they are not interested or too weak to try. A low birthweight baby has to start gaining weight immediately or get very sick so if nursing does not work immediately, then you have to give formula to that baby to start weight gain. I am guessing you also did not have any problems such as PCOS? I did. Women with PCOS have hormone problems so that their body might not be producing the proper amount of hormones to produce enough milk. That was another problem I had to deal with along with when your babies are not nursing right away it will impact your production.
My point being I know multiple women who had many difficulities nursing their babies for various reasons out of their control. The lactation consultants were important to them because they needed all the help they could get. I again am so glad it worked so well for you and your children. But, don't get smug about the fact that just because you didn't need help from a lactation consultant, that it would be the same for everyone.
