Re: Im worried, this is wrong..
Some kids are just less focused on eating than others. As long as she takes the breast when you offer it (at least sometimes) you are doing just fine. Her world is really expanding and opening up right now and it's a good sign that she is starting to explore it and become interested in other things.
I wouldn't worry too much about the nursing to nap thing, unless it is just getting to you to have to do it. They are pretty good about understanding that circumstances change and if mommy isn't there they will usually go to sleep just fine for someone else. It may take a bit of transition (or not, depending on the child and the caregiver), but she will definitely get used to falling asleep from someone else, esp since she is over a year. If she's nursing less at other times, I'd personally keep letting her nurse when she does want it to keep up supply and keep her interested in nursing- as long as it's working for you.
