I have 2 children 3 1/2 and 17 months, and I can remember when I was pregnant with my youngest I was always having a hard time catching my breath, or taking a deep breath. When I had her it felt like at the moment she came out she let go of my lungs and I could breathe again. A few months ago I started again with not being able to take a deep breath, and having the feeling to yawning to satisify the feeling. Sometimes it works, sometimes it don't. I have also noticed that if I am slouched I can't get a good breath, I have to be sitting up straight. Does anyone have any suggestion of what could be wrong. Other than this problem, I feel fine, I am what I call active, chasing 2 small kids around. It comes and goes, but if I wake up having a hard time, it will be like that all day. Other days I wake up fine and can breath fine all day. Please any suggestions or concerns will help.
