Aww, Char -
My 1st thought maybe that the move has unsettled then a bit, and with being ill too
Are they in the same room? could you maybe try the gradual retreat method? Settling them both down and you sit near the bed, gradually move bit by bit towards the door until they are asleep and you eventually reach the door.
Or maybe try some very low music/radio, just to distract them from what ever is upsettling them. I found its worked for O in the past when he's had these periods of not settling at bed time.
Ps, frig the neighbours - tell them to stick some ear plugs in.
They will settle soon enough, I just think you have all been through a lot these past few months and it probably getting to you all. xxx
