Your next task will be to make sure that your infant is properly secured in the car seat. Harness straps should be through the slots at or below the level of the rear-facing infant's shoulders, and should be tightened to one finger width at the baby's collarbone. Chest clips should be placed at the level of the baby's armpit. Make sure straps lie flat and are not twisted. To keep a newborn from slouching, pad the sides of the seat with and between the crotch with rolled up receiving blankets.
Many communities have specialists available to help assure proper installation.
Check with your local county health and police departments, and be sure to read the list of additional resources included with this article. Taking time to determine the best car seat for your baby will be time well spent. Remember to use your community resources and don't be afraid to ask for help - your efforts could save your baby's life.
