When you have gov take over your healthcare.
Had a doc in the UK threaten me with the same after my baby had a struggle to put on weight.
My older sister married a scrawny guy and their four children each started underweight, partly because of an infant allergy to corn and corn byproducts (corn starch, corn syrup, etc.). Before the last baby, they moved to Colorado where they had a new pediatrician.
During one visit some nosy do-gooder decided to report my sister to Child Protective Services who demanded to visit my sister's home once a week to observe her feeding the child formula (which contained corn byproducts). Instead of fattening her up, it just made the child sick.
My sister contacted her previous pediatrician who wrote a letter insisting that the other siblings also started out this way and that there was no sign of child abusive but the bureaucrats in Colorado were not persuaded.
To this day, I have never known my sister to be as furious as when the government told her she had to feed her baby something she knew would make the baby sick. It made her even angrier every time there was a local story of an abused child who needed CPS to intervene while, instead, they were bullying people like her for no reason.
The child, today, is healthy and fully grown with scrawny infants of her own.
