An 11-month-old baby cries and fusses when upset

A 11-month-old baby may cry and become fussy when upset, which could be caused by physiological factors or pathological conditions such as calcium deficiency or intestinal colic.

I. Physiological Factors

At 11 months of age, babies have not yet developed language skills. When experiencing physical discomfort, they express their needs through body language. For example, hunger, excessively high or low environmental temperatures, and similar conditions can cause a baby to become upset and cry. This is considered a normal physiological response. Caregivers should pay attention to the baby's physical needs—offer timely feeding and adjust clothing according to weather changes.

II. Pathological Factors

1. Calcium Deficiency

Crying when upset in an 11-month-old baby may also result from conditions like calcium deficiency. Calcium is an essential nutrient for the human body. A lack of calcium at this age can lead to overexcitation of the brain's nervous system, causing irritability and restlessness. Under medical guidance, calcium supplements such as calcium gluconate oral solution or calcium lactate oral solution may be administered.

2. Intestinal Colic

Intestinal colic occurs when smooth muscles undergo intense contractions, leading to intestinal spasms and pain. This discomfort can significantly affect a baby’s mood, resulting in irritability and persistent crying. Symptoms may be relieved through positional adjustments or gentle abdominal massage. If symptoms persist, parents should promptly take the baby to see a pediatrician.

In addition, mouth ulcers could also be a potential cause of fussiness and crying in an 11-month-old baby.
