Re: Just wanting to play?
What your daughter is doing, as far as patting or playing with the breast is quite common and perfectly normal.
As our babies get older and go into toddlerhood, it is absolutely acceptable and expected to want to set new limits on nursing. Making it work for mother AND baby is very important for extended breastfeeding and many mothers find themselves re-evaluating their expectations of themselves and their babies as far as nursing goes. It's okay to tell her that if she is not going to nurse, you're snapping the bra and moving on to the next activity.
To this point, usually the biggest source of time with mom has been nursing. To replace some of that with playtime away from the breast can reduce playtime at the breast. Reading a book, singing songs together, playing with toys or puzzles are ways that many mothers distract from the breast when the toddlers seem to want to just play.
