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.
Boiled Potatoes. If you're boiling potatoes for a potato salad or mashed potatoes, the best way to accelerate cooking time is to cut the potatoes into 2-inch pieces. Larger pieces take longer to cook, while smaller pieces tend to absorb too much water and then break down in the water. Pricking them may cause them to cook faster, but don't overdo it, or the small pieces will break as they cook. If you have more time, try boiling potatoes uncut in their skins.
