If you need to change your baby’s formula, it is not surprising to have questions on the best way to introduce a new formula. Before changing formulas make sure you have a chat to your health professional about the most appropriate product for your baby. You may need to introduce a new formula type or brand when finding one to suit your baby’s feeding needs.
When changing formula, it’s not uncommon for babies to initially be unsettled or detect small differences in taste. While some babies will transition to a new formula easily, others may experience minor digestive changes or tummy discomfort. This is normal while your baby’s digestive system is still developing, and should settle down within a couple of weeks. Digestive changes may include more wind or spilling than usual and changes in bowel motions including colour, consistency and frequency. These changes are usually temporary, so if you stick with the new formula most babies will adjust within a few days to a week or so. If baby remains unsettled or you have concerns always contact your health professional for further advice.
Here are some tips to help assist with this change:
As with all changes some babies are more sensitive than others. It may take time to transition to a new formula. If you can, avoid changing completely to a new formula in one day.
We recommend that you have about 1 weeks supply of the previous formula on hand, this way you can introduce the new formula gradually.
Introduce the new formula during the day, rather than at night so you can observe baby.
Always read and follow the manufacturer’s instructions for preparing the formula correctly, as preparation instructions vary between brands.
When choosing another formula, firstly make sure you speak to your health professional for advice on the appropriate type of infant formula for your baby.
The recommended method is:
Day 1 - offer just one bottle of the new formula in the morning, and for the remaining feeds offer the previous formula
Day 2 - offer two bottles of the new formula, for the remaining feeds offer the previous formula
Day 3 - offer three bottles of the new formula, for the remaining feeds offer the previous formula.
Continue this method until your baby has fully transitioned across to the new formula, this can take around about a week.
Another way to transition is to mix the two formulas together for several days before you introduce the new formula completely. You can do this by preparing a separate bottle of each formula (current and new) and then mix the two formulas together in another bottle. However, this method is less preferable, as it is more difficult to detect if something in the new formula doesn’t agree with your baby.
If you feel the formula you have introduced is not suiting your baby for any reason, there may be other formulas which will be better tolerated. Contact your baby’s health professional if you are concerned about any aspect of your baby’s health or have any questions.
