Again, this is very dangerous for children under 6 because their brains are still growing. Lead in your brain is poison . After you use the toilet or shower, the water in the pipes doesn't have as much lead. But, for every sink, you should run the water for a minute until the water is cold before you drink it or cook with it. Some people run the water first and then they put clean water in bottles and in the refrigerator so they do not need to run it again and again.
Hot water takes more lead from inside the pipes.
When you cook or make coffee or tea, start with cold water first and then cook it. These bowls are made by hand, not in a factory. The colors on these dishes usually have lead. Crystal wine glasses have lead too. If you put food in these dishes you may eat the lead.
