Re: Wean overweight toddler?
Unless she is nursing literally nonstop, I don't see how breastfeeding alone could be responsible for her high weight. Nor do I understand why weaning would be likely to "solve" the issue. Most babies max out their breastmilk intake at 19-30 oz per day (reference: http://kellymom.com/bf/pumpingmoms/pumping/milkcalc/). The recommended daily dairy allowance for a toddler is 2 cups a day. 2 cup = 16 fluid oz. Even if your toddler is nursing at the maximum intensity, getting 30 oz of milk in a day, she's less than 1 cup of milk per day over the RDA. While she is nursing somewhat more than SOME babies her age, she is by no means completely off the chart when it comes to nursing frequency, since she's nursing 6-7 times a day, max.
Based on my (probably slightly dodgy) estimates, I don't see why weaning would be in order. Regardless of your toddler's weight, it is important for her to get some dairy because she needs the calcium for bone/teeth development and the fat for brain development. If you wean her, she's still going to need to drink 2 cups of milk per day- right? It's just not going to be your milk.
That being said, if you decide you want to cut out some nursing sessions just to see if that has a salutary effect, you might want to consider doing some mother-led night-weaning. That seems like a decent compromise position between all-out mother-led weaning and baby-led weaning.
