H.,
Each child is an individual and there is no "pat" answer to your question. SOme babies are down to four or less nursings a day by one year, and others still nurse more frequently. My own two children were very different in their nursing patterns by a year. One nursed 4 times a day (morning, nap, evening and bedtime) and the other nursed for a minute many times a day (every time she fell down, bumped her head, had her feelings hurt....)
You will know when your child is ready to wean, because you will find yourself asking her, instead of her asking....
And, if you decide you are ready to waen before she is, you can distract her with other foods or activities.
Good luck and let me know if you want any more information,
