My 21 month old DD woke at 3 am Wed having been sick. Cleaned her up and she went back to sleep until am. Next day seemed fine, ate normally, etc. Same thing every night since, between 2 and 3 am. On Fri she did seem poorly and just wanted cuddles, felt slightly hot but not raging temperature. By yesterday afternoon, seemed much happier, was playing with her sister, etc. She has had a cold, so wondered if it was post-nasal drip making her gag, but I felt nauseous for a couple of days as well so likely to be a bug. But why is she only sick at night? It's not like any sick bug my other DD has ever had where she's been sick repeatedly for several hours and that's it. Am just giving her toast to eat today and see if she's any better tonight. Anyone else had this in their DCs?
