Anyone who is visiting estar, take her some healthy, home made things, like filled wholemeal pittas and a flask of creamy, milky coffee. You can't buy stuff like that in hospitals (only overpriced, dried up, hideous sandwiches and dishwater tea) and I could never leave my DD1's bedside unless my mum or DP was there and so I couldn't get a cuppa at all (shocking that the nurses aren't able to take care of mum and dad with a sandwich and a cuppa, when the wee ones are ill).
We were discharged for home care after two weeks. My DP was very, very good and would bring me in a supply of pittas and a big flask every day about 11am once my mum had got to our house to relieve him of the DTs. I didn't want to eat at all but it kept me on track at a time when all I could do was pace and sit on the edge of her bed around the clock.
estar our sick kids hospital had a loft for parents where you could shower and change (they also had rooms to stay in overnight but I couldn't be that far away from her bed). Make sure you are told everything that is available to make this time easier. Things like, sitters who can sit with your DS while you shower (if your DH is at home with the wee ones), the playroom should be able to make you up packs of playthings if he doesn't feel much like getting up, ask for a private room where he can have his own tv.....they don't usually charge, and they will give you one if no-one else is using it, but you will have to ask. There is usually a ward fridge you can keep some bits and bobs of food for him in if he's not enjoying the hospital grub. You can also bring in soups etc from home, it is allowed. They usually have supplies of duvet covers which they can put on his bed to cheer his room a little (esp since he's in for a wee bit) and/or you can bring in his own one.
Its the hardest thing trying to be at the hospital 24/7 and nip home to see the others. Be sensible and make yourself take care of you like you were your friend even if you don't feel like it. It is an insurance policy on you.
And.......don't worry too much about the others. You can catch up with them in time, a few cuddle-times at home in a while is all it takes for them to know you are still loving them. Right now, you have to be where you have to be and you must not overstretch yourself.
Expect to fall out with your DH soon or in a few weeks. Its a time of great tangles and if you know the reason behind the falling out (all this pressure) you will ride it well.
Shame we are not nearer. Thinking of you.
