Anyone else have this? DS2 19mths - sleeping then episodes of three/four short inbreaths then long exhale - like sobbing - can go on for 20/30 mins then wakes crying frightened. Can take ages to calm him, back to sleep then starts all over again. Tow/three times a week then ok for couple of weeks. Is it brain fizz? Growing/ or like a fit? Or nightmares?
Really puzzled and bit worried.
