it must be hard on the girls. Don't know if it would help but I might consider sitting each of them down individually, perhaps snuggled up in bed with the lights low (encourages confidences!) and let them talk about their fears. I've had to do this recently with mine because a change in circumstances has them acting up - the attention alone is helpful, feeling that they're being heard is good, but if you can give reassurances on some of their 'sillier' fears that can also ease some of their worries. Louisa especially might have some concerns which seem crazy to an adult ear, but which might be very real to her. The younger they are...!

look after yourself as well JJ - it's draining to be there for everyone else, and you know that you don't need to get sick!
