Has anyone else's DC had a strange reaction to pineapple or mango? When my DS was about 2 we had a couple of very odd nights when he'd go to sleep fine and wake at about 10 and then just be unable to go back to sleep, crying, talking hysterically in a way that sounded crazy (although lots of stuff sounds crazy at that age..), trying to sleep but failing, until about 5am when he'd eventually fall asleep. The only factor in common seemed be having mango and pineapple in the afternoon. I've never found a doctor or anything on line that seemed to back this up (except maybe some stuff about histamine intolerance and pineapple causing tummy pain) but ever since we've avoided both. Now he's starting school so I feel I need to try him on them - but can't bear the idea we may be up all night as a result!
