Introduce Formula Resolution For Free

A slow transition may help the baby get used to the new formula and help parents monitor and adapt to any new symptoms they may notice. It may take up to 1-2 weeks for a baby to adjust to a new formula.

To begin the transition with a 4-ounce bottle, you may mix equal parts of the old formula with the new formula for two to three days, then gradually provide only the new formula. If you are starting with a larger size bottle, you may transition more slowly.

When you're ready to introduce formula, offer a bottle of formula an hour or two after breastfeeding and then introduce an additional daily bottle-feeding session a few days later.

To begin the transition with a 4-ounce bottle, you may mix equal parts of the old formula with the new formula for two to three days, then gradually provide only the new formula. If you are starting with a larger size bottle, you may transition more slowly.

If you are combining breastfeeding with formula feeds, try to prioritise breastfeeding where possible. You could start by replacing 1 breastfeed a day with a bottle feed. When replacing a breast milk feed with a formula feed, it can take around 5 to 7 days for your breasts to adjust.

Dr Crosby: If you are making a transition and have some of the old brand left, you can start by mixing three parts old formula and one part new formula. If the baby drinks it, move to half and half and then 1/4 old and 3/4 new. Following that would be a full bottle of the new brand.

Many parents both breastfeed and formula feed at the same time. It's called supplementing, and it's perfectly okay to do this. Sometimes it may be necessary to supplement, such as when a mother has a low amount of breast milk, while other times it might just be more convenient to supplement.
