I would urge you to consider these things before choosing to wean your baby prematurely.
1. Milk supply is established on a supply/demand basis. This means your baby is getting what she needs from you if she is demanding. If you would like her to have more breastmilk you can opt to lower the amounts of other foods (particularly juices and purees) she is getting. Breastmilk is still superior nutrition.
2. Breastfeeding until 2 years of age provides the best immunity, brain power and mother/child bonding for your baby.
3. Little people, just like adults, go through periods of emotional upset/change. Your daughter might be going through some emotional changes that need your closeness and attention right now. She is expressing this by waking up frequently to nurse on you. If her emotional needs given time to resolve gently, this phase of night waking will likely come to an end soon.
4. Try "hands on". Give your baby a soothing massage before bedtime. If she wakes up a couple hours later, try to soothe her by stroking her and showing her closeness. If she still insists on breastfeeding then meet that need. Ignoring the need now will have the opposite effect. Emotional needs are just as important as physical needs. If your baby is hungry, you feed her. If she is crying/upset, you comfort her. At this age she is too young to understand manipulation, she is expressing a genuine need. Research shows that babies who are not left to cry become more independent and secure children. Yes, a baby that is left to cry will eventually stop, but at a high cost: Detachment.
5. The best way to wean a baby from the breast is child-led weaning. Based on her behaviors your daughter is not ready to wean. Forcing her to do so at this point is not advisable. Don't worry, she will not be on the boob forever. Enjoy this time with her, you can never get it back.
6. Seek out more information on breastfeeding and child-led weaning from www.askdrsears.com. Dr. Sears also has a Breastfeeding Book you can order.
Good luck to you and your little one! :D
Cheers,
