8 Reasons Why Your Baby Is Eating Less

If you notice that your baby is not eating nearly as much as food as they use to, this could be due to several reasons. While most of the reasons are not that serious, you should be concerned about prolonged periods of them not wanting to eat. It is always best to check with your pediatrician to make sure that your baby is okay. There are several reasons why your baby could be eating less, and below are eight of the most common. And while this list is not the end-all-be-all, it does contain some of the most widely known reasons as to why your baby does not want to each as much food.

1. Experiencing Growth Spurts

When your baby is growing and experiencing growth spurts, you will notice that their appetite levels change. You should know that this is very common, and you should not grow too alarmed. Your baby will soon likely regain their normal appetite, or they will develop an even stronger appetite. Your baby’s growth and growth spurts might indeed change their feeding needs. Do not be surprised if your baby’s food preferences and eating habits change as they grow.

2. Changes to Sleep

Changes to sleep are another reason as to why your baby might not be eating as much food. Previously mentioned growth spurts could cause your baby to sleep more and not want as much food. A sleepy baby does not want to eat as much. Your baby also might be more tired than usual from other factors. New stimulation or removal of stimulation can change sleep patterns, and your baby could also be adapting to fewer naps. Changes to sleep can indeed impact how much food your baby wants to eat.

3. Solid Food Introductions

You can begin giving solid foods to your baby sometime between the ages of four and six months old. If you notice, that four to six-month window is a pretty wide window, and there is not a guarantee to exactly when your baby will enjoy and be able to tolerate solid foods in their diet. All babies adapt to solid foods differently, and your baby will do this at the time best suited for them. Your baby could indeed be eating less because they are not quite ready for solid foods, so don’t be alarmed if you have to hold off on introducing solid foods to their diet. You should know that this is very common.

4. Possible Food Allergies

Food allergies could also be causing your baby to eat less. There are several signs you should pay attention to that might mean your baby has a food allergy. Among them are hives, vomiting, and wheezing. Rashes, swelling, and diarrhea are other symptoms you should pay attention to closely. If you notice any of those conditions above or anything at all unusual about your baby, you must consult with your baby’s pediatrician right away. Food allergies might not only impact your little one’s appetite. Food allergies can also be fatal for your baby. Take obvious signs seriously, and be sure that you are always on the lookout for potential food allergies.

5. Teething Has Started

You should be on the lookout for obvious signs that your baby is teething. Your child can begin teething anywhere from six months to 12 months after birth, so it is not uncommon at all for appetite changes for your baby to occur during this time frame. You should know there are all kinds of symptoms that can signal teething has started. A loss of appetite is only one of the symptoms that you could notice. When your baby’s mouth is sore from their developing teeth, do not be alarmed if they want to eat less.

6. Gas and Bloating

If your baby is dealing with more gas and bloating than usual, your baby might not want to eat nearly as much. Your baby has to develop its unique way of handling certain foods, and they also learn how to best digest those foods. Breastfeeding positions and baby food preferences and tolerances can cause gas and bloat. If your baby’s belly is a little bigger and their tummy is firmer than usual, they might be dealing with bloating and more gas. As a result, your little one might temporarily want to eat less.

7. Dealing with Constipation

Constipation is another possible reason for your baby’s loss of appetite. Any time that you notice your baby’s poop is not soft that could be a warning sign of current or forthcoming constipation. Fortunately, there are all kinds of great strategies to help your constipated baby. Belly rubs, warm baths, changes to food, and introductions to more water and liquid foods can help with your little one’s inability to poo.

8. Medical Issues

Medical issues like colds and infections can also cause your baby to eat less. While common baby illnesses could be the culprit, your child eating less also could be a sign of a more serious medical problem that has not yet been diagnosed. To make sure nothing too serious is wrong with your little one, you must check with your child’s pediatrician. You should consult with them at any time that you notice changes to your baby’s appetite. You must not hesitate. Delaying taking action about any sudden changes you notice with your baby could be the difference between life and death.


As you can see, there are all kinds of reasons that could be the cause of your baby eating less. Try not to let your baby’s lack of appetite cause you too much stress. You should know that your baby’s tastes and preferences will change, as will their ability to digest foods that you give them. You should be alarmed if their not wanting to eat is accompanied by other symptoms like fever, loose stools, regurgitations, dehydration, and skin irritations. The final say-so on why your baby is eating less must always come from your baby’s pediatrician.

  1. My baby never slept well (especially through the night) until I started using the website – that website has been by far one of the best things I’ve ever got my hands on to get him to fall asleep quickly. Best time is 45 seconds from awake to asleep! Can’t imagine life without it! I heard about it through a kindergarten teacher who uses it to put to sleep a group of 30 children. Check it out! SLEEPBABY.ORG 🙂 Best of luck to you and your family!

  2. If your baby won’t sleep, check out the sleep method from – Thank you SleepBaby for this brilliant method! My daughter now sleeps from 7pm to 6 or 6:30am every night with almost no night wakings. And even if she wakes, it’s usually just for a second and then she falls back asleep all on her own.

    Most nights I get my 8 hours of sleep and it’s just wonderful! I really feel like I understand her little body and mind and can address her sleeping holistically. I can’t thank you enough, Kacey and the team!
