We have found an allergy that David has, and now we can sleep a little better. Here's the story so far. Whenever David went to bed, he would get congested. So we changed the sheets and pillow cases. No help. We then washed everything, sheets, cases, pee-pad, and clothes in a organic detergent, and we used no fabric softener things during the drying. No help. Was he allergic to laying down? Did he just need to be held all the time? Fortunately, no. One of Julie's night time routines was to put on a moisturiser. So she decided to skip it and see how David did. He was clear! So it looks like he is allergic to either sunflower oil, or Isopropyl Palmitate or methylparaben. But at least he is sleeping better now.
