Switching brands or introducing formula for the first time?
We know sometimes it takes a little time to find the right formula as every baby is unique.
Whether you’re introducing mumamoo for the first time or switching from another brand, a slow and gentle transition is best. We also suggest transitioning gradually between stages where possible. This gives your baby time to adjust to the new taste and smell while helping their little tummy time to adjust.
And remember, if you’re ever unsure, it’s always best to check in with your GP or healthcare professional for guidance.
👉 Follow our transition guide below for a gentle, step-by-step move to mumamoo.

Can I transition my baby from another formula brand to mumamoo?
Yes, you most certainly can. All formulas vary in taste so it can take time to comfortably transition to a new brand. A slow and gradual change between formulas is recommended to help your baby adjust to the new taste and smell and avoid refusal or change to your feeding routine.
Before switching formulas, we always recommend speaking with your GP or healthcare professional for advice. Every baby is different and it’s important to ensure that any specific nutritional needs are met, particularly if your baby has low birth weight or is premature. Your healthcare professional can work with you to advise if your new formula preference is suitable for your baby’s needs.
Babies’ tummies can be sensitive to change so a gentle transition will assist their digestive system as they adapt to the new formula. During this transition, it’s not uncommon to notice some changes, particularly in the colour, smell and consistency, of yes you guessed it, poo 💩
We don't recommend mixing two brands in the same bottle. Instead our table below provides an example of a suggested introduction. It’s important to note any changes in poo, spitting up, comfort, how much they are eating/drinking or anything else you notice. You may wish to keep paper notes as a handy record.

How do I transition my baby from exclusive breastfeeding to mumamoo?
The below guide can also be used when introducing formula from exclusive breastfeeding. A slow and gradual introduction is recommended to help your baby adjust to the new taste and smell and avoid refusal or change to feeding routine.
We do not recommend mixing breastmilk and formula in the same bottle. Instead, we recommend introducing the number of bottles per day slowly as suggested in the examples provided eg ½ bottle of mumamoo for the first 2 days, then increase to 1 full bottle for another 2 days.

How do I transition between Stages?
Every baby is different, so we do suggest a slow transition between Stage 1 & 2 to give tummies time to adjust. You may like to follow our Transition Guide below. The difference between our Stage 1 and Stage 2 is in the Whey to Casein Protein Ratio and the levels of Vitamins and Minerals.
Stage 1: Whey 60%, Casein 40%
Stage 2: Whey 50%, Casein 50%
Stage 3: Whey 40%, Casein 60%
Both breastmilk and cow’s milk include Whey and Casein protein. Whilst the ratio of Whey/Casein varies, the average ratio in breastmilk is 60% Whey and 40% Casein during early lactation. This then decreases to approximately 50% Whey and 50% Casein in late lactation. We have reflected this in our formulation. Also the levels of vitamins and minerals vary slightly between Stage 1 and Stage 2 and this is based on babies dietary needs and requirements as they grow (babies are often consuming solids between 6-12 months so receive vitamins and minerals through their food also).
If you’re not sure about changing stages, we’d suggest asking your GP or health professional as they will be able to advise specifically for your baby’s needs. Any other questions be sure to get in touch, we’re here to help!
Suggestion on a gentle transition to mumamoo:
Please note: the transition can take 7 days or longer before exclusively being fed with the new brand.
Introduce one bottle of new formula per day. Morning feeds are recommended to give your baby time to digest the new formula throughout the day. Continue this for a few days then slowly increase the volume of feeds using the new formula per day.
For a more gradual transition you may choose to introduce ½ bottle of the new formula per day, then increase to a full bottle per feed over subsequent days. If you choose to introduce ½ bottle ensure you feed your baby the remaining ½ bottle with your existing formula for that feed. Do not mix different formula brands or breastmilk to make 1 bottle.
