All you need is a phone line! All phone lines have a constant flow of voltage, around 40-70 volts (up to 100 volts when it rings!), but you can't just plug stuff into it and expect it to work.
Children older than 5 and more than 40 pounds must ride in a booster seat until the child is 8 years old or is taller than 4 feet 9 inches. Anyone over the age of 8 must be protected by a safety belt.
Do not place the shoulder belt under the childâs arm or behind the childâs back. Older kids get weighed and measured less often than babies, so check your childâs growth a few times a year. Generally, kids need to use a booster until they are at least 4 feet 9 inches tall and weigh between 80 and 100 pounds. For most kids, they will be between ages 8 to 12 years old. Talk with everyone who drives your kids so they understand that booster seat use is a must when your child is in their vehicles.
