I was 24 when my daughter was born. I was determined that I was going to breastfeed her. My husband and family knew what I wanted to do, so I had a lot of support.
When she was first brought to me the nurse helped me with all my questions. They had a nursing specialist that would help with all your questions and concerns. After you leave the hospital you can always call the nurses station with all your questions.
If this is what YOU want to do, do not give up. There are some women that are not able to breastfeed. If you are able to and you want to, keep trying.
I picked up a book on clearance somewhere called: "So, That's what they're for" written by Janet Tamaro. (you can probably have your local library get it. I did just verify it is listed at bn.com)
Let me tell you, this is the best book I could of read. It confirmed to me that I did want to breastfeed. I would describe the book as a down to earth book written by your girlfriend. It talks honestly about pregnancy and breastfeeding.
I do not like to read at all. I read this book from cover to cover. It is not medical mumbo jumbo. It is is just plain info that we can all understand.
Your doctors should be able to tell you what support groups are around.
I rented a breast pump instead of spending tons of money on one. I think at the time it was approx. $35 per month. It was great because I did not spend alot of money and the woman who I rented it from was trained to help with all breastfeeding questions and concerns.
Giving birth and breastfeeding are easy. My daughter went to kindergarten last year and I cried. Time went by so fast.
You will be just fine when labor starts. After you call your doctor, she/he will walk you through everything. Think positive, it will be a great experience.
