A child who has been on formula milk up to the age of 3 now drinks very little. They eat very little, just a bit of white rice, and have never eaten any meat, vegetables, or eggs. They don’t like them and often vomit when they try to eat. Occasionally, they can eat a little egg white. Oral liquid and digestives have been used for treatment, but the effect was not significant. Help is needed, unsure whether the issue lies with medication or the care methods.
