A2 Step One
Tizzie says in her feeding book:
Many of the formulas described above are also subdivided into two or three ‘steps’ or ‘stages’ according to the baby’s age. Basically, each step is the same base formula with additional ingredients added for different stages of a baby’s development.
• Step one also known as stage one or starter formula: is for newborns to six or twelve months, depending on the brand.
• Step two also known as stage two, progress and follow-on milk: this is marketed as a formula for babies aged six months and older as it contains more iron and protein than step one formula.
• Step three also known as stage three and toddler milk: developed for toddlers aged twelve months or older. It contains supplemental vitamins and minerals.
In my experience it’s best to buy only a step one formula in Australia, regardless of your baby or toddler’s age. Recently I have become aware of problems when babies are introduced to step two formulas. I have many clients contact me when their six-and-a-half month old, previously contented baby suddenly starts catnapping, early-rising and night-waking and, in some cases, vomiting. After careful consideration and ruling out many things I have found the one thing that most of these babies have in common is they have been started on step two formulas. After advising parents to move back to the step one formula the babies have returned to their happy, settled and well-rested selves again. If you are following my advice for feeding solids, your baby will obtain enough protein and iron from his food so there is no nutritional benefit to be gained from switching to a step two formula.
I have seen very similar problems when parents try to introduce their twelve-month-old baby to cow’s milk or step three formula, which contains large amounts of sugar. (I talk extensively about cow’s milk later in this book on page 190, and for information on weaning to cow’s milk see page 191.) While this problem does not affect all babies, my advice is to keep your baby on step one formula from birth through toddlerhood until he is ready to drink cow’s milk.
