My 2 week old daughter breaths very loudly and fast at night, should i be concerned?

Don't worry : Marie- congrats on ur new baby! Don't worry about the breathing at night; their respiratory centers in the brain are still developing. U r probably worried about SIDS; to prevent it we recommend: putting her to sleep on her back, breastfeeding, vaccinations on time, sleeping in a separate crib or bassinet, at most one thin blanket not covering the neck or mouth, and avoidance of tobacco.
