Re: tell me about nursing a 14 month old
Congratulations on nursing to 14 months! It only gets better from here on out.
Is the all-night nursing a new thing, or has your baby always been a frequent night-nurser? If it's a new thing, it could be due to teething- many babies increase nursing frequency when their gums are bothering them. If she's always been a frequent nurser, then it may be that the night-nursing is at least in part a habit: many babies like to use the breast to soothe themselves to sleep, and don't like to accept substitutes for that pleasure. I suggest taking a look at Elizabeth Pantley's book The No-Cry Sleep Solution for Toddlers and Preschoolers, which can help you handle this situation in a gentle way.
While sickness and menstruation often cause a dip in supply, I would not worry about "losing" your supply. As long as you nurse on demand, your supply may dip but it will quickly bounce back.
Child-led weaning is, in my experience, a very slow and gradual process. It took my child 3 years to get to the point where she was only nursing once or twice a day. Kids do develop the ability to accept comforts other than the breast, but don't expect that ability to arise until 18 months-2 years at least.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
