If your baby cries for longer than 3 hours a day, your baby might have colic. Colic is not caused by another medical problem. Many babies go through a fussy period. Some cry more than others.
If you have a baby with colic, you are not alone. 1 in 5 babies cry enough that people call them colicky. Colic usually starts when babies are about 3 weeks old. It gets worse when they are between 4 and 6 weeks old. Most of the time, colicky babies get better after they are 6 weeks old, and are completely fine by the time they are 12 weeks old.
Infantile colic - self-care; Fussy baby - colic - self-care
Colic normally begins at about the same time every day. Babies with colic are usually fussier in the evenings.
Colic symptoms often begin suddenly. Your baby's hands may be in a fist. The legs may curl up and the belly may seem swollen. Crying may last for minutes to hours. Crying often calms down when your baby is tired or when gas or stool is passed.
Even though colicky babies look like they have belly pain, they eat well and gain weight normally.
Possible Causes of Colic
Causes of colic may include any of the following:
- Pain from gas
- Baby cannot tolerate certain foods or certain proteins in breast milk or formula
- Sensitivity to certain stimuli
- Emotions such as fear, frustration, or even excitement
People around the baby may also seem worried, anxious, or depressed.
Seeing Your Baby's Health Care Provider
Your baby's provider can often diagnose colic by asking you about the baby's medical history, symptoms, and how long the crying lasts. The provider will perform a physical exam and may do some tests to check your baby.
Avoiding Your Baby's Triggers
Foods that are passed through your breast milk to your baby may trigger colic. If your baby is colicky and you are breastfeeding, avoid eating or drinking the following foods for a few weeks to see if that helps.
- Stimulants, such as caffeine and chocolate.
- Dairy products and nuts. Your baby may have allergies to these foods.
Some breastfeeding moms avoid eating broccoli, cabbage, beans, and other gas-producing foods. But research has not shown that these foods can have a negative effect on your baby.
Other possible triggers include:
- Medicines passed through breast milk. If you are breastfeeding, talk to your own doctor about the medicines you take.
- Baby formula. Some babies are sensitive to proteins in formula. Talk to your baby's doctor about switching formulas to see if that helps.
- Overfeeding or feeding the baby too quickly. Bottle feeding your baby should take about 20 minutes. If your baby is eating faster, use a nipple with a smaller hole.
Talk to a lactation consultant to learn more about the possible causes related to breastfeeding.
Comforting Your Baby
What comforts one baby may not calm another. And what calms your baby during one episode may not work for the next. But try different techniques and revisit what seems to help, even if it only helps a little.
If you breastfeed:
- Allow your baby to finish nursing on the first breast before offering the second. The milk at the end of emptying each breast, called the hind milk, is far richer and sometimes more soothing.
- If your baby still seems uncomfortable or is eating too much, offer only one breast as often as you want, over a 2 to 3 hour period. This will give your baby more hind milk.
Sometimes it can be really hard to stop your baby from crying. Here are techniques you may want to try:
- Swaddle your baby. Wrap your baby snugly in a blanket.
- Hold your baby. Holding your baby more may help them be less fussy in the evening. This will not spoil your baby. Try an infant carrier that you wear on your body to hold your baby close.
- Gently rock your baby. Rocking calms your baby and can help your baby pass gas. When babies cry, they swallow air. They get more gas and more stomach pain, which causes them to cry more. So babies get in a cycle that is hard to break. Try an infant swing if your baby is at least 3 weeks old and can hold their head up.
- Sing to your baby.
- Hold your baby in an upright position. This helps your baby pass gas and reduces heartburn.
- Try placing a warm towel or warm water bottle on the baby's stomach.
- Lay babies on their stomach when they are awake and give them back rubs. DO NOT let babies sleep on their stomachs. Babies who sleep on their stomachs have a higher risk of sudden infant death syndrome (SIDS).
- Give your baby a pacifier to suck on.
- Put your baby in a stroller and go for a walk.
- Put your baby in a car seat and go for a drive. If this works, look for a device that makes a car motion and sound.
- Put your baby in a crib and turn on something with white noise. You can use a white noise machine, a fan, vacuum cleaner, washing machine, or dishwasher.
- Simethicone drops are sold without a prescription and may help reduce gas. This medicine is not absorbed by the body and is safe for infants. A doctor may prescribe stronger medicines if your baby has severe colic.
Colic Always Goes Away
Your baby will most likely outgrow colic by 3 to 4 months of age. There are usually no complications from colic.
Parents can get really stressed when a baby cries a lot. Know when you have reached your limit and ask family members or friends to help. If you feel like you may shake or hurt your baby, get help right away.
