When a 5-month-old baby experiences cough and vomiting due to a cold, symptoms can be relieved by taking oral medication, keeping the abdomen warm, drinking plenty of warm water, and using Dinggui’er belly button stickers. If the baby refuses to drink water, try making pear water or brewing sugared calcium water, which are often more appealing to babies. Additionally, to prevent heat syndrome, giving a small amount of water-diluted honeysuckle essence is also a good choice.
