Pros: Has allowed me to breastfeed my child.
Cons: You have to clean it with every use (even in the middle of night)
When in the hospital I was having such trouble nursing my daughter. The LC came to see us and said that my daughter had a short tongue and I had flat nipples. We used the shield and like magic I was breastfeeding. I have pumped, used the breast shields to draw out my nipples in between feedings and the nipple shield during feeding. My nipples have not changed (I was told they would get pulled out by using all of this stuff). I was worried about all the claims of reducing my milk supply so I tried several times to use the shield for latch and then switch to bare nipple. As soon as I take the shield off my nipples go flat again leaving by child frustrated wondering where her nipple went. The days that I decided we would wean from the shield were the worst days, my daughter and I both ended up crying all day. I decided this was crazy. My daughter is now 6 weeks old and my milk supply is abundant (I could be a wet nurse!). She is gaining weight rapidly and I am still using the shield. I am not a professional but from my personal experience I felt I needed to write to tell other mothers out there not to let these "professionals" scare you. If it is working for you and your baby is healthy then keep it up! We all have to do what is best for us and our babies.
