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.
Cover with an inch of water and stir in a teaspoon of salt. Cook the potatoes until tender: Bring the water to a simmer over medium-high heat; adjust the heat to keep the water at a gentle simmer. Cook until the potatoes are tender all the way through when pierced with a fork, 8 to 12 minutes. Exact cooking time depends on the size of your cubes and the type of potatoes. For full step-by-step instructions, see How To Boil Potatoes. Drain and rinse the potatoes: Drain the potatoes and rinse them under cool water.
