Usually about a half hour, but we don't eat at home.
It takes less time if I've set everything out the night before. Then, I just wake up, put my clothes on, brush teeth and hair, then wake up dd, put her clothes on and brush her teeth. If she wakes up easily, we could be out in 15 minutes. If she wakes up hard or cranky, or wants to nurse, it can take 45 minutes.
