Goodness gracious, you're doing all of the right things, it sounds like you are certainly busy pre-op.

Rhia is very fortunate to have your strength and care. Before you know it, this will be behind you and she'll be on the mend.
There is no greater gift to a child facing a dificult surgery than to have their parent(s) as a living example of courage.

Pace yourself and realize that everything may not get done, but the important things will .. and everything else will fall into place, no worries.
Ena and I always kind of use the time around surgery as a mini-vacation, we have good reason to set the world aside and relax and have fun.

We will be thinking of you both.
