While many of today's top baby food companies are touting their credentials as "allergen-free," Square Baby meal plan ($79 for two weeks) is doing the opposite and leaning into recent research. Square Baby is taking a cue from recent studies and are incorporating proteins that you won't see in most other brands, like egg, fish, and soy. Square Baby even designed their allergen-introduction meals to deliver the appropriate amount of egg, milk, and peanut protein to be in alignment with expert recommendations to help reduce baby's risk of developing allergies to these potentially triggering foods (assuming baby eats two or more of the Square Baby meals per week).
