One of the best things you can do to prepare for an emergency with your baby is to take a baby/infant First Aid and CPR class. Nothing can replace in-class, hands-on training. This post is just to provide information and is not meant as a class replacement for a professional instructor. Contact your local Red Cross and see when you can sign up.
Take a class. Even if you can follow written directions, it can’t hurt to take a class and get certified in infant and child CPR. You’ll get to see these techniques performed in person and ask the instructor any questions.
Get rid of anything blocking the airways. If there is something in your child’s mouth, try sweeping it out with your finger. If the airway seems blocked, perform first aid for a choking baby.
Shout and tap. Decide whether CPR is necessary. Call out your child’s name and gently tap him on the shoulder. If there is no response and the baby is not breathing (or not breathing normally), position the infant on his back to begin CPR.

You will want to be able to access the signs of a choking baby,
If a baby is suddenly unable to cry or cough, something is probably blocking her airway, and you’ll need to help her get it out. She may make odd noises or no sound at all while opening her mouth. Her skin may turn bright red or blue.
If she’s coughing or gagging, it means her airway is only partially blocked. If that’s the case, let her continue to cough. Coughing is the most effective way to dislodge a blockage.
If the baby isn’t able to cough up the object, ask someone to call 911 or the local emergency number while you begin back blows and chest thrusts. ~BabyCenter
