Is your DD interested in learning letters or how to write her name? This is the biggest factor IMO.
Here are some things that may help (IMO)...
Environmental print- reading signs, looking at catalogues, a cereal box, tin can etc. Talking about what you see around you is a great incidental way of teaching letters and symbols. Walks around the street , home or looking at some junk mail (toy catalogues are great) is all it takes to go letter spotting.
With writing....Start with letters in DD's name if that is the direction you want to go (if your goal is DD being able to recognise and then write her name). Point the capital letter out in books, on tv, wherever you see it. For example, my DD3 (aged 3) is Hannah, we have pointed out the capital H to her in books etc and now whenever she sees a H she says "Oh, look a H like in my name". She recognises the letter that starts her name.
For learning your name, having it as a sight word can be handy too, you could make your own flashcard of DD's name and place it with a photo of her. A child being able to pick what their name 'looks' like can help with pre-writing and early writing skills as they learn the 'shape' of their name.
Writing letters doesn't have to be confined to paper either, try writing in the sand with a finger, in fingerpaint, in a tray full of flour, make letter shapes with playdough...lots of different ways to write that can be fun.
Tracing sheets can help as you progess, especially helping with the proper formation of letters and the way in which they are written (starting point of letter, direction of pencil to form letter etc). Tracing sheets also help with sizing of letters and honing fine motor control.
I also agree that schooling will 'teach' your DD more formally through the use of phonics/reading/writing programs and activities that reinforce that learning.
