Do not force the eyelid open. Follow similar guidelines if a hazardous substance gets on your baby's skin. Remove contaminated clothing and pour water onto the affected skin for 15 minutes. Then wash the area gently with soap and water and rinse. You'll need to keep your wits about you and remain calm.
Time is of essence, so act quickly.
Call 911 or your local rescue squad. Open your child's mouth and remove any pills, berries, or leaves you see. Open his airway by gently lifting his chin with one finger and tilting back his head with another. Check his breathing by putting your cheek to his mouth and nose, and feel and listen for breathing. Look to see if his chest rises and falls.
