Answer:
Life in the ghettos was usually unbearable. Overcrowding was common. One apartment might have several families living in it. Plumbing broke down, and human waste was thrown in the streets along with the garbage. Contagious diseases spread rapidly in such cramped, unsanitary housing. People were always hungry. Germans deliberately tried to starve residents by allowing them to purchase only a small amount of bread, potatoes, and fat. Some residents had some money or valuables they could trade for food smuggled into the ghetto; others were forced to beg or steal to survive. During the long winters, heating fuel was scarce, and many people lacked adequate clothing. People weakened by hunger and exposure to the cold became easy victims of disease; tens of thousands died in the ghettos from illness, starvation, or cold. Some individuals killed themselves to escape their hopeless lives.
Every day children became orphaned, and many had to take care of even younger children. Orphans often lived on the streets, begging for bits of bread from others who had little or nothing to share. Many froze to death in the winter.
In order to survive, children had to be resourceful and make themselves useful. Small children in the Warsaw ghetto sometimes helped smuggle food to their families and friends by crawling through narrow openings in the ghetto wall. They did so at great risk, as smugglers who were caught were severely punished.
Many young people tried to continue their education by attending school classes organized by adults in many ghettos. Since such classes were usually held secretly, in defiance of the Nazis, pupils learned to hide books under their clothes when necessary, to avoid being caught.
Although suffering and death were all around them, children did not stop playing with toys. Some had beloved dolls or trucks they brought into the ghetto with them. Children also made toys, using whatever bits of cloth and wood they could find. In the Lodz ghetto, children turned the tops of empty cigarette boxes into playing cards.
