You may start introducing herbs and spices to your baby if she is over 8 months old. Introduce one herb at a time and practice the 4 day rule to see if there are any allergies. Since babies are used to bland food, just a bit of herb will be enough. You can try oregano, dill, cilantro or ginger. http://www.easy-homemade-babyfood.com/can_babies_eat_spices.html
Yes sure if she's 8 months or older. You can start with cinnamon, garlic powder or even pepper. http://wholesomebabyfood.momtastic.com/tipspices.htm
Rosemary for chicken and potato. Cilantro and parsley for almost anything.
I started up with cinnamon, basil and oregano for my kids.
thanks
