If the baby doesn't feel unwell now, you don't need medication. Usually, give the baby more foods with high calcium content and more sunshine to increase the absorption of calcium, so as to ensure that the baby has enough sleep. Usually, the diet is diversified. When the appetite is bad, you can give the baby this medicine for regulating the spleen and stomach function, such as Jianpi Granule and Erbao Granule, to wish the baby grow sturdily.
