Re: Talking to my 3 year old about weaning
You might want to look into the idea of a weaning party. That's when the child picks the date and aspects of the celebration (type of cake, venue, present) and agrees that after that landmark, there will be no more nursing. The average age of self-weaning is probably around 3-5. But the are kids who nurse longer and kids who nurse for less time than that, so I wouldn't take the average as a good predictor of what any particular child will do.
Do you have limits on nursing? With my toddler, we usually nurse only at certain times (wake-up, pre-nap, pre-bedtime), and only for as long as I want (usually until I count to 10). Having those limits has allowed me to have a lot more control over our nursing without shutting DD down entirely.
You can definitely wean while potty training, but they are both processes that can proceed unpredictably, for extended time periods, and it can be hard to know how those two phases are going to impact each other.
