A good idea to pack a "coming home" bag.
I had to come home wearing my slippers when I'd had DD, and she was covered in a towel (it was winter).
DH had taken my shoes and coat and everything home the day I had her to create some space.
When we knew we might be coming out, I left him a long answerphone message to tell him what he needed to bring. Car seat, coat and shoes for me, blanket for DD.
Because I was running out of money for the phone, I rang my mum to ask her to ring him and tell him:
"we might be coming out but not sure, please listen to my message, and stay off the line as I'll ring you if we are coming out."
Mum "Yesss. I'll tell him you're coming out and he's to ring the hospital."
Me: "No. We might be but I'm not sure. I'll ring HIM."
Mum: "Yep. You're coming home and he's got to ring the hospital."
Me: "Nooooooooo!! I don't know that we are coming home. I'll ring him. Can he stay off the phone, but listen to the answering machine."
Mum: "OK. I'll tell him to ring the hospital because you're coming home."
Me: "aaaaargh!"
I got back to the ward and as I passed the desk he was on the phone
When he arrived to collect us I asked where my shoes were and got "Shoes, what shoes?! If you wanted shoes why didn't you ask me to bring them in?" Followed by "What answerphone message?"
Gaaaah
Oh, I think I needed to tell that story!
