Booster seats that only fit into Group 2 are less common. Groups 2 & 3: for children weighing 15 - 36 kg (33 - 79 lbs), roughly 4 to 11 years. These seats are adjustable to cover a wider range of weights and heights and so can last for several years.
As you cut your potatoes place in a pot of water to avoid discoloring. Cook small 1/2 inch pieces 2 minutes in boiling water and drain. If you have larger pieces or whole potatoes, boil up to 10 minutes and drain. You want the potatoes to be hot through, but not over cooked. Remember no larger than 2 inches.
For mashed potatoes, potatoes should be boiled for not more than twenty minutes. Pick the best potatoes, wash them, peel them and then boil water. To maintain the beautiful golden color of potatoes, you may add a little vinegar. After twenty minutes check each potato with a fork. Insert it in the potato and see if it has boiled properly or not. If the potatoes are bigger in size, you can boil them for ten minutes more and then check them again.
