baby food

So Im looking at baby food recipes and some of them are saying recommended for ages 6+ months for example spinach....i was gonna make my baby who is 5 months spinach puree tonight.......i was wondering who has not followed these recommendations or if i should really follow them. She is exclusively breast fed and gets 2 teaspoons of solid food (that i make myself) almost every night. She absolutely loves her solid foods so far. Ive done apple, pear, sweet potato, and avocados.
