If your little one is fussy, or suffering from gas, she may be showing signs that she's not tolerating her current infant formula well.

Speak with your baby's doctor right away. He or she may suggest changing to another infant formula.

If your doctor thinks this may help, the good news is that switching her to a different infant formula is easier if you offer the new formula in stages. This helps wean your baby from the original formula. By combining formulas and gradually increasing the amount of new formula, your baby will be less likely to notice any change in taste. As the chart below shows, this process should take about a week:

		Current Brand		New Formula
	Day 1	Current Brand only		0 parts
	Day 2	3 parts	+	1 part
	Day 3	3 parts	+	1 part
	Day 4	2 parts	+	2 parts
	Day 5	2 parts	+	2 parts
	Day 6	1 part	+	3 parts
	Day 7	1 part	+	3 parts
	Day 8	0 parts	+	New Formula only

Here's what to expect from switching from another infant formula to NESTLÉ^® GOOD START^®:

• NESTLÈ^® GOOD START^® is the only iron-fortified infant formula made with 100% whey protein and uses a unique, patented process to partially break down the whey protein into smaller pieces making it easy to digest.* This means your baby may eat more often than if you were to use another kind of formula. However, in total, your baby will consume about the same amount of infant formula.
• Babies on NESTLÉ GOOD START infant formula may have more stools a day. The stools may be soft, unformed, like the stools of the breast-fed babies, and yellow to greenish in colour.
