I have a lot of health issues but I can totally understand why someone would do this.  Attention and sympathy.  All the attention and care you would get from people with zero actual worry.  

They are never the kind to quietly care for their child without asking for help.  Nope they can grift attention, money and gifts without ever worrying their child will actually be dead. Which gives them an extra layer of giddiness, pulling one over on all the gullible people.  It’s gross but I get why people do it because I have met people who seem to care about nothing but attention.

Some of them put their children through unnecessary operations or end up killing their children through poisoning.
