After all those options, I'm sure you are wondering what sets the information and guide found here apart from the others.
A couple of things. First, my recommended food introduction schedule is geared toward catching and preventing food allergies and / or sensitivities. Many mainstream pediatricians suggest starting infants on cereals and grains. The problem with this is grains [cereals included] are some of the most difficult foods to digest along with meats, dairy, and many fats.
In addition to this, I also start with vegetables rather than cereals and fruits. Vegetables are the most important foods you can give your baby. They are full of essential vitamins and minerals and are, almost exclusively, low in sugars. It's important to remember that our bodies, both infant and adult, are wired to want sugar and fat in mass quantity when it is available. This is part of our survival mechanism and is what allowed human beings to survive over the years. These days what was once a key to survival is now an addiction. Starting with low-sugar [yes, even natural sugar] foods helps provide your baby with the taste for veggies. The exception is avocado, the food I recommend you begin with.
I've also provided some important tips to help you navigate through the baby food confusion as well as a couple resources I have found to be really helpful throughout the journey.
May your baby be nourished by the food you provide.

Note: I don't take either of these as gospel [for example, I disagree with food introduction schedules] but both provide great starting points and are extremely useful in guiding through the baby food preparation, storage, and safety process.
