Sorry to hear about your Dcs who are struggling with their health. Glad to hear that many are settling in.
My dd has been poorly all term on and off, with tonsilitus, she is going to have them out as they are so bad, but consultant wants her to be infection free so will be in the new year and she will have to miss the first week of term. At least if it is planned she can let her lecturers know. We had hoped to wait until Easter, but she cried and said the thought of another term feeling so ill was not fair and the uni GP is in agreement. Haff The uni GP retested her for glandular fever, as she had it last year, so may be worth looking into that.
We popped up to see her last week, removed 1 black bag of rubbish from her room, helped her tidy, filled her fridge and freezer. Amazed to find she put the hoover round that night after we left.
My sister is a uni lecturer and she says they are only half cooked at as adults at this stage :)
