Breastfeeding is a wonderful source of nourishment and bonding for many mums and babies, but it isn’t the only way to feed your little one. Parents may choose to switch to formula due to low milk supply, returning to work, medical reasons, or personal preference.
At Baby’s Pantry, we understand that breastfeeding doesn’t always go as planned. Some women experience pain, stress, or latching issues. Others simply find that formula fits better into their family’s routine. Whatever your reason, choosing formula is a valid and loving choice.
In this guide, we’ll walk you through how to introduce formula to your breastfed baby step by step. We’ll also share what signs to look out for and tips to help make the transition as smooth as possible, especially if your little one is reluctant to give up the breast. Formula feeding can also bring flexibility and gives both parents a chance to share in those special feeding moments.
When should you introduce formula?
The best time to switch from breastfeeding to formula will vary from one family to another. There is no one-size-fits-all answer, and it’s always a good idea to speak with your health visitor or another trusted healthcare professional when making decisions about your baby’s feeding journey.
The World Health Organization recommends exclusive breastfeeding for the first six months, with continued breastfeeding alongside other foods up to two years or beyond. However, this guidance may not be practical or possible for everyone. If breastfeeding is becoming overwhelming, painful, or simply isn’t the right fit for your lifestyle, it’s completely acceptable to consider formula earlier.
Every parent’s situation is different. The most important thing is that your baby is well-fed, thriving, and that you feel supported in whatever feeding path you choose.

Which formula should you choose?
Once you’ve decided to make the switch to formula, it’s important to choose one that meets your baby’s nutritional needs. Factors such as age, dietary requirements, and any sensitivities or allergies should all be taken into account.
If your baby has been breastfeeding well and shows no signs of intolerance, a cow’s milk-based formula is typically a good starting point. European brands like HiPP and Kendamil offer formulas made with high-quality ingredients, designed to be gentle on developing tummies and nutritionally complete.
For babies with a sensitivity to cow’s milk protein, you may wish to explore goat’s milk formulas, which can be naturally easier to digest. Brands such as Nannycare and Holle offer goat’s milk options that many families find suitable. There are also specialist formulas available, including anti-reflux and comfort formulas, for babies with specific medical or digestive needs.
European infant formulas are often preferred for their clean ingredients, strict regulations, and commitment to quality. At Baby’s Pantry, we stock a range of trusted brands to help you find the right fit for your baby’s unique needs.

The strategy: How to go from breast milk to formula
When moving from breastfeeding to formula, a gradual approach often works best. If your baby has never used a bottle before, try offering expressed breast milk in a bottle first. This helps them get used to the feel of the bottle without introducing a new taste at the same time.
You can also mix breast milk and formula in the same bottle. A good starting point is 75% breast milk to 25% formula, increasing the formula ratio slowly over time. This gentle change gives your baby time to adjust to the flavour and texture of formula.
Another option is to alternate feeds, offering one bottle of breast milk and the next with formula. This works well for some babies, but not all. Some may find the switch between tastes and textures a bit confusing, so it’s best to watch for any signs of preference or fussiness. Many mothers choose a routine that includes both bottle feeding and breastfeeding. For example, you might use a formula during the day due to work or other responsibilities, and then continue breastfeeding at home. The key is to do what works best for you and your baby, while making the transition as smooth and stress-free as possible.

Tips to overcome stubborn babies
If your baby is finding it hard to adjust to bottle feeding or formula, you are not alone. Many babies need time, patience, and a little creativity before they take to the bottle. Here are some gentle techniques that may help ease the transition.
One method is to help your baby get used to the bottle nipple by placing a small amount of breast milk on it before feeding. This familiar taste can encourage them to latch and make the bottle feel less unfamiliar.
Using a slow-flow bottle teat can also help. These teats are designed to mimic the natural flow of breastfeeding, so your baby still has to suck and work for the milk, just like they would at the breast. This can make the switch feel less drastic.
If possible, ask someone other than the baby’s mother to offer the first few bottles. Babies are often highly attuned to their mother’s scent and may become confused when she offers a bottle instead of the breast. Having another caregiver give the bottle can help avoid this association. If that’s not an option, holding something that smells like the mother, such as a worn T-shirt, may also help.
Most importantly, take your time. If your baby refuses the bottle, try again later without pressure. Many parents find success by starting with breast milk in a bottle, then slowly mixing in formula and increasing the ratio over several days. Keep calm, stay consistent, and trust that your baby will adjust at their own pace.

Conclusion
Raising a baby is a beautiful journey, but it can also bring challenges. Many mothers face situations where breastfeeding exclusively is not possible. This could be due to work, health concerns, discomfort, or simply personal preference.
If you decide to transition from breastfeeding to formula, take your time. A slow, gradual approach is often the easiest path for both you and your baby. With patience and consistency, most babies adjust well to the change.
