Hi and congratulations on your newborn! I'm so sorry you and your wife are having such a difficult time getting started with breastfeeding. You have gotten some great advice here from PP's. I want to second the discussion that constant nursing in a newborn is very normal. With the chomping/latch issue, however, you do want to make sure to keep track of wet and dirty diapers to make sure that baby is getting enough to eat. What is your baby's current diaper output? As you asked about earlier, yes, feeding the baby is the most important thing to consider. However, IF supplemental feeds are needed, there are alternatives to using a bottle which can provide baby the nutrition while avoiding nipple confusion and keeping baby on track to be able to nurse effectively. It sounds from your initial post like you have seen several LC's? It can be very frustrating when you get a bunch of different advice. Was there anyone that you felt comfortable with that you could continue to see/keep in contact with? Supplemental feeds can be given by finger feeder (this is also sometimes used to help train babies to suck), by syringe, by spoon, or by cup. There are feeding cups designed specifically for newborns. When you saw the LC, did she weigh the baby before and after a feed to see how much he was getting? Did anyone suggest a nipple shield? Nipple shields should be used as a last resort since they can sometimes cause problems if not used correctly, but they can be good for babies who are not able to latch. I have seen them used effectively for babies with the "chomping" response. Nipple shields should be used under the supervision of an LC since a proper fit is essential.
In response to your concerns regarding the Zoloft--yes, having to take a medication while nursing can be scary. However, many many medications are considered safe while breastfeeding, and I know several mothers who have taken Zoloft. As someone stated in another thread regarding this same issue, nursing and taking the Zoloft is generally considered to be healthier for the baby than either of the alternatives--continuuing to nurse with a depressed mom or discontinuing breastfeeding. I really hope you ALL start to feel better soon! Keep posting here for support and ideas.
