I'm desperate. For the past three nights my dd (nearly 3) has gone to bed with just the usual amount of fuss only to wake screaming about two hours later. She's done a very loose, almost diahorrea -type pooh and is complaining that her bottom hurts, to the extent that it can take half an hour for her to allow me to get near her to change her. There's no nappy rash and no cuts in her anus (I got the doc to check). I get her back to sleep with cuddles and calpol and an hour later we have the same again, but with even more hysterics and this can go on for another couple of hours before she falls into an exhausted sleep. She's fine during the day, but the nightime stuff has gone on for the past three nights and I'm really beginning to lose the plot, especially as just as I get her off the baby (4 months) usually wakes up. We've been to the docs (twice) and he said it might be worms, but would the reaction to this be so extreme - she really does go ballistic, won't lie or sit down, starts beating her bottom and screaming for it to go away - also he didn't see any evidence when he looked, though he's sent off some tests. I'm treating her for that anyway, but otherwise am at a loss. Has anyone else come across this. She was unwell (fever, cough, cold) last w/e and has recently started asthma drugs, but the doc assures me this is unrelated. All help appreciated.
