Yes, particularly if the child is left in a dangerous situation. Child abandonment can result in the child being taken away from the parent and put into a foster home. It is rude and irresponsible to leave a child in a toy-shop or any other store to use it as a playroom while you do your shopping!
The differences is that the legitimate child is the legal child while the illegitimate child is the illegal child.
Ask child services if you can leave. There are too many unanswered questions before you can be assisted here.
no
That is actually considered abuse because it wouldn't be fed for that amount of time and that is illegal. Take your dog with you, leave it at a friends house, or take it to kennel while you're gone.
Leaving your child alone for that long isn't illegal. It is the parents opinion to gauge weather your 14 year old kid can keep your 6 year old safe and sound for 3 days. Truthfully I wouldn't leave them alone. If anything happens to them there is a good possibility that you could be charged with endangerment of a minor in my view. But no. It is not illegal to leave your kids home alone.
It is not illegal to leave your car running while waiting for someone in a parking lot as long as someone (a licensed driver) is in the car.
It is illegal to smoke cannabis, let alone look after a child whilst under the influence of it
only if the child is 11 or older
Yes, as long as there's no arrears.
Yes, it is illegal to hold a baby in a car while driving in most places. It is important to use a proper child safety seat or restraint system to ensure the baby's safety while traveling in a vehicle.
The interesting aspect of this situation is that while you may be an illegal alien, it is possible that your child isn't, depending upon where the child was born. All people born in the US are automatically US citizens, even if their parents were in the country illegally at the time of the birth. So, your child might have all sorts of rights under US law that you as an illegal alien don't have, including the right to be supported. If, however, you and the child are both illegal aliens then you would not be awarded child support, but merely deported if the government learns about you.
