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.

If your outbreak was caused by external contact with an allergen, clearing that allergen from your skin right away can help lessen the severity of the reaction. Avoid soap products that contain sodium laurel sulfate as this chemical often irritates an allergic reaction. Unscented, gentle cleansers such as Dove, Aveeno, Cetaphil, or Shur-clens are good options. Many lotions and ointments are available over-the-counter at supermarkets or drug stores that can provide immediate relief for symptoms like itching and burning. Try some of the following: Calamine Lotion, which should be applied as needed unless otherwise directed. However, be careful not to leave calamine lotion on the skin too long as this can irritate the rash more. Aloe Vera should be applied two or three times a day until the area begins to heal. Hydrocortisone cream, sold at most drug stores and supermarkets, is available without a prescription and can provide temporary relief of skin rashes caused by allergens. Low-strength (.5 or 1%) hydrocortisone creams are typically applied one to four times a day until symptoms begin to clear up. Hydrocortisone cream comes in the form of an ointment, lotion, foam, liquid, gel, spray, and a moist towelette. Choose whichever form you're most comfortable using, and follow the instructions on the label.Ointments tend to be more soothing to irritated skin. Lotions can sting and are best for covering larger areas. For some, over-the-counter lotions and creams further irritate their skin. If that's the case for you, you may want to invest in some natural remedies. Clay can provide a cooling sensation and thus decrease the need to itch a rash. Use virgin, untreated clay. Mix the clay in a bowl or cup of water until it has a creamy consistency, dab it on itchy or irritated areas, let it dry, and then peel it off. If peeling the clay is causing any further irritation, try re-wetting the clay and gently removing with a soft, wet towel. Apple Cider Vinegar has anti-fungal and anti-bacterial properties that relieve itching. Dab a few drops on a cotton ball or washcloth and apply to the affected area. Peppermint or peppermint leaves can provide an instant cooling sensation that relieves irritated skin. Crush up some peppermint leaves and rub them directly on the skin. Basil leaves contain anti-itch compounds called camphor and thymol. Rubbing fresh basil leaves on the skin can relieve some symptoms. Oatmeal's anti-inflammatory properties allow it to soothe itchy, irritated skin.An oatmeal bath can help reduce or relieve symptoms. Fill a bath with lukewarm or cold water and then add half a cup of oatmeal to it. Soak for 15 to 20 minutes. It's best to use colloidal oatmeal, which is oatmeal ground into a finer powder. It dissolves easily and leaves less mess to clean up afterwards. If unavailable, you can grind regular oatmeal into a powder using a mixer. The oats can also be placed in a muslin bag or cheesecloth and hung in the water. Some people find adding a few teaspoons of extra virgin olive oil to their bath helps, as it is a natural moisturizer. If you choose olive oil, be careful when getting in and out of the tub as it will make the area slippery. Sometimes the simplest solutions can be the best. Wet a soft towel or washcloth with cool water and apply to the rash 2-3 times per day for 15-30 minutes. The cool water can lessen the sensation of itching and may reduce swelling as well.
Summary: Wash your skin right away with cool water and soap. Use lotions or ointments. Try hydrocortisone cream. Use natural treatments. Try an oatmeal bath. Use cool water.
