When it comes to changing your baby’s formula, many parents have one common question “How long does it take for a baby to adjust to formula change?”. In this article, I will answer the question and try to explain everything regarding the topic.

How Long Does It Take For Baby To Adjust To Formula Change

There is no exact answer to this question, but according to many professionals, and based on my own experiences, your baby will need at least 7 to 14 days to adjust to formula change. If you decide to change your baby’s formula, what you will need the most is patience.

Don’t expect your baby to adjust to changes from day one since many factors impact this process. Babies are sensitive, and most of the time, they avoid changes. There are many types of formulas, and finding the best one is a bit challenging.

Why Change Baby’s Formula? – Reasons

Sometimes you might notice your babies having some difficulties and are not able to adapt to the formula you are using for them, indicating that it is time to switch to another one.

Worth mentioning is that parents shouldn’t change the formula randomly; there must be reasons for that since babies might struggle to adjust to formula change. If they are okay with the one you are using, then don’t experiment much.

Pediatrician’s Recommendation

When it comes to baby formulas, pediatricians know the best, and before deciding, consult them. Sometimes your doctor might recommend switching the formula as your baby grows up.

Babies’ ingredient requirements change once they get older, and this is the main reason why the pediatrician might recommend changing the baby formula and continuing with another one that has more iron and some other ingredients that play a vital role in the healthy development of babies.

So, this might be one of the biggest reasons you will need to switch to a new baby formula and see whether your baby will like it.

Your Baby Doesn’t Like The Formula

If your babies don’t like the formula, they will show you many signs, and most probably, you will need to change the formula and start using another one.

Diarrhea after every bottle feed is one of the significant signs that shows that the formula you are using is not the right one and your baby doesn’t like it.

Many other digestive issues and allergic reactions might occur if your babies struggle with the formula you use to feed them. Accordingly, you need to pay attention to those signs and consider changing the formula.

Formula Type

Formula type is one of the reasons why you may need to switch to another one. Most of the baby formulas use cow’s milk protein, but some babies might have lactose intolerance, and this causes some issues that lead to a change in the formula.

Many parents also consider switching from non-organic to organic baby formulas, for better nutrients and so on.


As babies get older you will need to feed them less frequently but with an increased amount of formula. Basically, your babies require many cans of formula per month.

Due to this reason, you might want to switch to a less pricey one and save some money. Budget is also a factor in why many parents want to change their babies’ formulas.

Tips On How To Switch The Formula

If you are worried about how you will switch to another formula and you don’t know what you need to consider, here I will show you some tips so you can effortlessly change the formula and decide on the best one.

Consider All Types Of Formulas

First and foremost, before deciding on a new baby formula, you have to consider the issues your baby has with the formula you are using, and what are the ingredients of the formula.

There are many of them available on the market, and deciding on the best one is not easy. If your baby has lactose intolerance, then you should go for a formula that has soy milk proteins.

However, if you have a sensitive baby, then a formula that is made of hydrolyzed proteins is the best pick. Pay attention to the vitamins and minerals that the formula contains, and also go for the one that is very similar to breastmilk.

Switch To Another Formula Gradually

The best way to switch to another formula is to do it gradually, but this depends on whether you change it for your and your baby’s preferences or some allergic or digestive issues.

If your babies have allergic reactions and some digestive problems due to the formula you use, then you can switch to another one immediately.

Whereas, if you are switching to another formula due to your preferences or you just want to use a formula with different nutrients, then switching gradually is better.

Side Effects Of Switching The Formula

You can never know whether you have switched to the right baby formula or not. If the formula you switch is not the right one for your baby, then there will be some side effects due to this, and you might need to change it again, unfortunately.

If you notice that your babies have more grass, they are frequently crying or waking up, vomiting, and becoming fussy, then all of these indicate that the formula you switched is not the right for your baby.

Yet, do not let this disappoint you since you should have patience and wait at least one week to see whether your babies will adapt to their new formula.
