Reasons Behind Bottle Refusal

There can be several factors contributing to formula fed baby suddenly refusing bottle. Let’s delve into some of the common reasons why this might occur –

Transitioning from Breastfeeding to Bottle Feeding

If you have recently transitioned your baby from breastfeeding to bottle feeding, it is not uncommon for them to resist the change. Breast milk has a distinct taste and warmth that may differ from formula. Your baby may need some time to adjust to the new taste and texture. Mixing breast milk with formula can help ease the transition. Additionally, warming the bottle to a comfortable temperature can make it more appealing to your baby. This is one of reasons behind formula fed baby suddenly refusing bottle.

Temperature Preferences

Babies have individual preferences when it comes to the temperature of their milk. Some babies prefer it warm, while others prefer it at room temperature. Experiment with different temperatures to find what your baby prefers. Remember to test the temperature on your wrist or the inside of your forearm to ensure it is not too hot before offering it to your baby.

Teething Discomfort

Teething can be a challenging time for babies, and it can affect their desire to suck on a bottle. In most cases, teething is reason formula fed baby suddenly refusing bottle. The pressure from sucking may worsen teething discomfort, leading to bottle refusal. If you suspect teething as the cause, try offering a teething toy or a cold washcloth to soothe your baby’s gums before offering the bottle. Adjusting the feeding position to a more upright angle can also alleviate any discomfort.

Illness or Discomfort

Babies who are unwell may find it uncomfortable or painful to feed. Common illnesses such as colds, ear infections, sore throats, or thrush (a yeast infection in the mouth) can affect their appetite. If you suspect that your baby is experiencing any of these health issues, consult with their pediatrician for appropriate treatment and guidance.


Babies are easily distracted, especially as they grow older and become more aware of their surroundings. External stimuli such as noise, visual distractions, or even the presence of other people can divert their attention away from the bottle. Create a calm and quiet environment for feeding to minimize distractions and help your baby focus on the task at hand. This is one of the main reasons behind formula fed baby suddenly refusing bottle

Introduction of Solid Foods

Another major reason for formula Fed Baby Suddenly Refusing Bottle is when your baby begins to explore solid foods, their interest in the bottle may diminish. They may be more focused on discovering new tastes and textures, which can lead to a decreased appetite for milk. Offering solid foods before offering the bottle can ensure that your baby’s hunger is satisfied while still providing them with the necessary nutrients from milk.

Nipple Preference or Flow Issues

Babies can develop preferences for certain nipple shapes or flow rates. If your baby is frustrated by the flow of milk, it may be worth trying different nipple sizes or bottle brands to find one that suits their needs. Some babies prefer a slower flow, while others may require a faster flow. Observing your baby’s feeding cues and adjusting accordingly can help resolve any nipple or flow-related issues.

10 Ways to deal with Formula Fed Baby Suddenly Refusing Bottle

1) Understanding the “Bottle Strike” Phase

A formula fed baby suddenly refusing bottle may be going through a phase known as the “bottle strike.” This usually happens around the 2-4 month or 8-month mark and is characterized by a sudden refusal to drink from the bottle. There are several reasons this can occur:

Developmental Changes

Around this time, your baby’s cognitive and motor skills are developing rapidly. They’re becoming more perceptive and are able to recognize and analyze what goes into their mouths. If they sense that something is different, they may refuse it.

Involuntary to Voluntary Sucking Reflex

Newborns possess an involuntary sucking reflex that enables them to feed immediately after birth. However, around the 2-month mark, this reflex transitions into a voluntary action, which means they can control their sucking and feeding. This change can lead to a temporary refusal to drink from the bottle.
