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.
Turn the burner on high and bring water to boiling. Reduce heat to medium low or low. Cover the pan with a lid. Cook the potatoes in gently boiling water until tender, about 15 minutes for cubed potatoes and new potatoes and 20 to 25 minutes for quartered potatoes. Drain the potatoes in a colander.
