Some babies readily accept any formula being offered to them whilst others may refuse or take time to gradually transfer across. Slowly changing formulas is ideal when transitioning from one formula to another. A sudden switch to another brand or formula type can lead to fussiness, feed refusal and sometimes constipation.
Start by introducing one bottle with new formula at the first feed of the day or when your baby is particularly hungry.
Offering the new formula in the morning can reduce the risk of potential fussiness in the evening.
Substitute one bottle each day with the new formula, so over 5 – 6 days the baby has time to adapt to the new formula.
Avoid changing any other feeding associations such as; when you sit to feed your baby or changing the bottles or teats, as too many changes may cause confusion.
