DS is 20 months and I have a 5 week old too. Right now I am tandem nursing but ever since I had the baby I feel like I want to wean DS. The problem is, he nurses constantly (always did before DD came too) and has a mouth full of teeth and it hurts my nipple when he nurses. I try to get him to be more gentle but he doesn't understand. And when I try to nurse my baby he wants to be right there. It's hard to nurse both of them at the same time although I do it sometimes. If I don't give in and let him nurse when he wants to he has a meltdown. Sometimes when he nurses it gives me the same feeling as when somebody scratches their nails down a chalkboard. I get the creeps. That's what makes me feel guilty. I love the little guy so much and I don't want to hurt him but he's totally not ready to wean and I don't know what to do. I knew things would be hard when I had the baby.
