Sorry that I have to bring up this topic, but DS5 has been having interupted sleep for the past 3 nights, he wakes up wriggling around and crying that his bottom is sore, the next morning and all day long everything is fine then an hour or so after he goes to bed it starts, also he has suddenly started eating like a horse. afer a thorough internet search this morning (including your threads) I concluded that threadworms were the culprit! so I went to the pharmacy and got ovex. i cannot find any info that tells me how long it takes to kill the little buggers. I gave the pill to him at 3pm put him to bed at 8 with vasaline on his bottom and now 10:30 he just woke up screaming again. I looked at his bottom with a torch and did not see anything ?? and now I am starting to question if this is threadworm ?? hmm
