Babies 4 months do not love breastfeeding may be a normal anorexia period, which usually improves on its own. However, it may also be related to thrush, dyspepsia, upper respiratory tract infection and other pathological factors, with different causes and different treatments, and should be treated promptly. A short period of anorexia at around 4 months of age may be associated with discomfort due to teething, which is a normal phenomenon and usually resolves on its own. If it is caused by thrush, there is no need to take oral antifungal medication, but can be relieved by topical application of mycotoxin, and at the same time, attention should be paid to breastfeeding hygiene. If it is indigestion caused by not eating milk, parents should avoid feeding too much milk at once or the baby’s abdomen is cold, but also give the baby bifidobacteria, lactobacillus granules and other drugs to promote digestion, regulate intestinal flora. There may be other reasons why your baby doesn’t like breastfeeding at 4 months, so you should consult your doctor in time to find out the cause and get appropriate treatment if necessary. Please follow your doctor’s instructions when taking medication.
