Sounds like a lot of drama and trauma! I's so sorry you're stressed!
I really suggest you contact your local local La Leche League Leader. They are accredited and offer medically accurate information and support completely free of charge. They even have meetings you and your toddler could go to so you could consult with other mothers who have nursed babies into toddlerhood. Their Web site is www.lllusa.org.
You have a lot of gentle options to help with weaning at this age, and as time goes on you'll have more and more. I go with the "don't offer, don't refuse" method and just avoid sitting in our comfy nursing spots. But, if my child clearly needs to nurse, I never deny it. It's just too beneficial in too many ways, and weaning is a process, not an event. Actually, you HAVE been weaning him for months--since he took his first bite of solid food, so you could just say you ARE weaning and continue the pricess gradually in a non-traumatic way.
The best book I have even found on this topic is "How Weaning Happens." Another excellent one is "Mothering Your Nursing Toddler." You could purchase either through LLL directly or borrow them for free from your local group. They are sanity-saving resources that have ideas you won't find in any other parenting book. One of my favorite strategies suggested in "How Weaning Happens" is telling your child "we'll nurse until I could to 10/sing Eensy Weensy Spider." Then, it's up to you if you count or sing quickly or slowly. You don't have to completely cut him off to be working on weaning--even reducing his time spent at the breast little by little is part of the weaning process.
A very wise mother friend of mine told me that the word "wean" comes from the same Latin root as the word "to ripen." She likens the mother to a tree and the baby to a fruit. When the fruit/baby is ripe and ready, it is easy to pluck it from the tree with little effort. If the fruit/baby is not yet ripe or ready, it will take a lot of rough and stressful tugging to pull it off the tree. Sounds like there's a lot of tugging at your house! Any chance you could just back off the weaning for awhile?
It's also important to remember you have to wean TO something. You cannot just eliminate this very important facet of your child's development without offering an equally appealing and conforting replacement. This is where dad needs to step up, in my opinion. Personally, I accidentally weaned my first child to Winnie-the-Pooh videos and pretzels, but I was a bit smarter with my second and he weaned to extra snuggling and playing and reading with dad.
Please know that it is NOT a "weakness" to respond to your child's crying. you are biologically programmed to respond like a mother because you are a mother. Recognizing and meeting your child's need is not "caving in," it is being wise and intuitive. The more completely you meet this very legitimate need, the more quickly and thoroughly it can go away and you can both graduate peacefully to the next stage of your relationship.
I'm not advocating you continue breastfeeding if you are not longer comfortable with it, but you should know that it is developmentally appropriate for a 19-month-old to nurse both for nutrition and comfort. Also, the American Academy of Pediatrics recommends mothers continue to breastfeed until their baby is *at least* one year old and "thereafter as long as is mutually desired by mother and baby." UNICEF and the World Health Organization both recommend that mothers breastfeed until their baby is at least two years of age, and the last Surgeon General of the U.S. said "It's the lucky baby who is breastdfed until age 2." Worldwide, the average age of weaning is between two and four. So you're not the only one and you're *not* out of the healthy norm, American culture and expectations are.
It does make sense that as he hits a million different developmental milestones he would cling to the experience that has brought him comfort and reassurance all his life. I think it's terrific he turns to people and not things for comfort--congrats on raising someone who understands that turning to loved ones in times of stress is what will bring peace.
Babies are for loving. As you know, they are not babies forever and these needs do not last forever. Hang in there. I'll be thinking of you. And do consider calling a LLL Leader. She will be so helpful!
Best wishes!
