Re: food strike?
Actually, at 11 months breastmilk is still capable of meeting all her nutritional needs, provided that you nurse on demand. It's pretty typical for babies to still be mostly or even completely breastfed up to or even past their first birthdays. My first kid survived and thrived on breastmilk and a teaspoon or two of solids per day until she was around 15 months, when she suddenly decided that she liked solid food. Another thing that is completely normal is for a baby to go on a solid food jag or a solid food strike.
Just be patient, and remember that you can't make a baby eat! All you can do is put a variety of healthy choices in front of her, and wait for her to decide that they are delicious.
