Make sure other children in the family know not to share combs, brushes, towels, or hats with each other or their friends.

If your baby goes to Childcare and there's been a Lice infestation, send him with his own Lice-free infant seat, bedding, and so on.

And check his scalp often so you can treat him promptly if needed.

Fortunately, Lice survive without a human host for only a day or two.

The Nits take a week to ten days to hatch, though, so to play it safe, follow these guidelines:

1. Machine wash in hot water all the clothing and bed linens your baby came in contact with during the two days before treatment began. Put these items in the dryer on a high setting for at least 20 minutes.

2. Put all stuffed animals, Comforters, and clothing that can't be washed in a sealed plastic bag for two weeks. An alternative suggested by the National Pediculosis Association is to put items that can tolerate the heat in a hot dryer for 30 minutes.

3. Soak combs and brushes in Rubbing alcohol for an hour, or wash them with soap and hot water.

4. Vacuum the floor, furniture, and car interior, including your baby's car seat. Don't use Insecticidal sprays, which can be toxic if inhaled.

Because Lice can travel from one head to another, getting rid of the bugs and Nits right away can keep them from spreading to other children and family members. But eliminating Lice isn't always easy.

Lice-killing shampoos, called Pediculicides, might sound convenient, but they're not safe for babies or toddlers and probably not very effective, either. Even on older children the use of these shampoos is controversial.

Many parents and experts say Lice have become resistant to the products. And some parents are uncomfortable with the idea of putting pesticides on their child's scalp and hair.

The best way to get rid of the critters, according to the National Pediculosis Association (NPA), is also the most basic: by removing the Lice and Nits manually. Here's how:

•  Use your fingers, or a nit comb if your baby has enough hair to warrant it. The NPA sells a comb called the LiceMeister, designed according to the latest research. With rounded teeth nearly twice as long as other Lice combs, it gets all the way through thick hair without painful tugging. You can order one from the NPA's website or by calling (888) 542-3634 in the United States.

•  Work in a well-lighted area to make the Nits and Lice easier to spot. Some parents say the best place is outdoors in the sunlight, weather permitting. A strong pair of nonprescription reading glasses, available at most drugstores, can be an invaluable tool.

•  Divide hair into sections with clips and go through it section by section. Have a container of hot, soapy water next to you and use it to clean the Nits and Lice off the comb frequently.

•  Some parents report that using oil on the hair makes it easier to comb out the Nits, while others say it makes the Nits harder to see.

•  Nits more than half an inch from the scalp are usually empty shells that don't need to be removed — but you'll probably want to get rid of them anyway.

•  Continue to check your baby's scalp thoroughly and use your fingers or a nit comb to remove any Lice and Nits every three or four days for several weeks.

•  Check all other family members (adults and kids) for Lice and Nits as well, and follow the same removal procedure as soon as you spot trouble. There's no need to treat pets, because human Lice don't live on animals.

Parents have tried various other remedies with mixed success. Some say they've gotten rid of the pests by covering their child's hair with vegetable oil or mayonnaise for several hours, then washing it out thoroughly. This seems to suffocate the Lice, preventing them from laying more eggs.

Be very cautious about using any Home remedies on your baby. If you're in doubt, ask your baby's doctor what she thinks.

Your little one may have picked them up from an Infected sibling or at Daycare.

Lice are crawling insects, so they can't Hop, Jump, or Fly, but they can travel from one head to another by direct contact.

Off the scalp, they live for a day or two and can be passed along when people share pillows, hats, and so on.

It's a myth that Lice are a product of poor hygiene or poverty.

Head lice are remarkably egalitarian and can flourish in even the wealthiest communities.
