Summarize the following:
If you have a newborn baby, you should invest in a rear-facing infant car seat. These seats are designed to be safer for babies that weigh between 22 and 35 pounds. When sitting in the seat, the baby's head should be at least 1 centimeter (0.4in) away from the side of the seat. If not, the car seat is too small. Once the baby weighs more than 35 pounds (or their head is less than 1cm away from the edge of the seat) you will need to upgrade to a bigger car seat. Convertible car seats are a good option if you plan on using the car seat over a couple of years. They can be converted from a rear-facing seat for small infants (weighing up to 40 pounds) to a front facing seat for older infants and toddlers (weighing up to 70 pounds). Keep in mind that it's best to keep the seat in the rear-facing position for as long as possible, as it is the safest option for your child. Your child will need to be moved to a bigger seat when the top of their ears is level with the top edge of the seat. These car seats are best for children who are over the age of four and weigh at least 40 pounds. They are front-facing and use the car's regular seatbelts to secure the child. The child has outgrown their booster seat when the headrest is set to its highest level and the child's shoulders are two inches above the opening of the straps. Once the child has outgrown this booster seat, they should be able to sit in the car independently, without the use of a seat. Sometimes it's possible to get a baby seat that can easily be removed from the car and attached to a baby stroller. This is very convenient, as you won't need to remove the child from one seat and strap him or her into another. These types of baby seats and strollers are usually sold in a set.

summary: Choose an infant car seat if you have a newborn baby. Get a convertible car seat that will last from infant to toddler. Go for a belt-positioning booster seat if your child is over four. Consider getting a car seat that will fit into a baby stroller.

Fill a large bowl with water, then add the seaweed. Gently press down on it to submerge it, then leave it along for 10 to 15 minutes. It is read when it is plump and supple. Pour the seaweed through a strainer. Squeeze it by the handful to get rid of any excess moisture. Place the seaweed onto a cutting board. Use a sharp knife to slice it into -inch (1.27-centimeter) wide strips. Pour the sesame oil into a small bowl. Add the rice vinegar, salt, and sugar. Mix everything together with a form or mini whisk. Transfer the seaweed to a serving bowl. Sprinkle some sesame seeds over it, then add the dressing. Toss everything together to evenly distribute the dressing. You can serve it cold or at room temperature. If you have any leftovers, cover them, and store them in the fridge for up to four days.

summary: Re-hydrate the seaweed. Drain the excess water from the seaweed. Chop the seaweed into thinner slices, if needed. Prepare the dressing. Combine the dressing with the seaweed and sesame seeds. Serve the salad.

If your home has central heating and cooling, then you most likely have a central thermostat to control it. Thermostats, whether programmable or not, will have many similar settings, including fan options, heating options, and cooling options. With fan options, you will most likely have "on" or "auto." By choosing "on," you will engage the fan on your system to circulate air through the home without heating or cooling it. The fan will run for as long as the "on" option is engaged. The "auto" option will only engage the fan when either the heat or air conditioning turns on and needs to be circulated. The "on" option for the fan is generally considered an energy waster since it will require a decent amount of energy to move that much air on a constant basis. Due to this most people only ever leave the fan set to "auto." Many people use the "on" option simply to flush air out of a houseif something burned while cooking and you want to circulate enough air to clear the smell, for instance. Depending on your model of thermostat, you will likely either have a small switch on the thermostat's faceplate or a cycle button to cycle between heating, cooling, and off options. You can prep the system to cool the home by moving the switch or pressing the button until you reach the "cool" setting. You will see a number on the thermostat display. This number is the ambient temperature in your home. Use the up and down arrows on the thermostat to set the temperature you want the home to reach. You will see a different display number come up that corresponds to the temperature you set. You will likely hear the system click as it engages and turns on the air conditioning to lower the temperature in the house to what you have set. The system will run until the house reaches the chosen temperature, and then it will automatically turn itself off and only reengage when the internal thermometer registers that the home is warmer than the set temperature. You can use the same switch or button to cycle the system to "off" at any time. Setting the heat for your thermostat is very similar to setting the cooling option. Use the same switch or button to cycle through until you reach "heat." You can then use the same set of arrows you used to set the cooling temperature to set the heating temperature. Again, the system will only run when the internal thermometer registers that the ambient room temperature is colder than the set temperature. You may also see an "EM heat" or "emergency heat" setting on your thermostat, especially if you live in an area prone to bitter cold conditions. This setting corresponds to a separate electric heating unit in the home in the event that the larger system breaks or freezes over during winter. While it does not hurt to test the emergency heating option periodically, you should stick to the standard heat setting for day-to-day use.
summary: Learn the differences between settings. Turn on the fan. Set the air conditioner. Set the heat.
