My son just turned 3 months old and this has only happened one other time. He literally started bloody murder screaming out of no where. He's eating now but that wasn't a hungry cry or an attention cry. He was in pain somewhere. He was screaming and hyperventilating and and coughing, running out of breath, stopping breathing, turning red... and it just started out of no where. He was perfectly fine seconds before. The only other time that happened was a few weeks ago when I had him in his bouncer right outside the shower. He does have reflux and bad gas/colic, but as I mentioned this type of cry isn’t the usual and has only happened one other time.
