My DD is 10 weeks old, every so often it seems like she is gasping for breath, she sounds like she is trying to take in lots of air but not breathing out again straight away, there is also a high pitched gasping noise, any ideas what this could be or why she has only just started doing this, or help on what i can do? I have read that it could be due to nasal blockage or it could be due to reflux. any help advise would be greatful thank you in advance
