Babies sometimes sound like they are having a breathing fit. It's relatively normal, though Read this : www.kidshealth.org
But rest assured that it's normal for young infants to breathe somewhat irregularly.
When an infant is awake, his or her breathing rate may vary widely, sometimes exceeding 60 breaths per minute, particularly when the little one is excited or following a bout of crying. Newborns will also commonly have periods during which they stop breathing for about 5 to 10 seconds and then start up again on their own. This is known as periodic breathing, which is more likely to occur during sleep and is considered very normal. However, if your infant turns blue or stops breathing for longer stretches of time, it's considered an emergency and you should contact your child's doctor immediately or go to the emergency room.
