DS has been having some wind problems, on colief now and has been reasonably settled these past few days. Round about the same time I cut out citrus fruit and greens i.e brocolli, sprouts etc (I do love my veg!!) as all was going well last night I introduced some green veg with dinner; DS didn't have a great night and again today he's been grouchy. That's approx 12 hours - could it be the green veg??
