Re: Staying attached to the breast
the general advice about weaning is if your kid is acting like yours is, then the weaning is happening too fast. now, sometimes, that's unavoidable, but most of the time it's best to just take it a bit slower.
i'm not sure what advice to give you on TTC. there is no guarantee you'll get pregnant faster if you wean. how long have you been trying? your daughter is only 12 months, and average return of fertility is 15 months, i think even without breastfeeding (someone check me on that please). so it's entirely possible you could spend a nightmarish 3 months weaning your daughter and not be pregnant any sooner. many, many mamas get pregnant again while still bf. so there are just no guarantees here and you have to weigh your desire to continue nursing against your timeline for getting pregnant again and the built-in uncertainties of that timeline. also remember that most women lose most of their milk while pregnant (mine was mostly gone by 12 weeks, which is typical) so while you might be able to comfort/dry nurse through the pregnancy (lots of people do, but most people find it very unpleasant at least part of the time), she will likely not be getting very much nutrition during the pregnancy.
