I would only suggest getting out of the house as much as possible, and then, when you're inside, letting things GO. Like, maybe you could get the kids into bed with you with a bunch of books and puzzles and lounge, baby LOUNGE. I'm actually serious here. I've found that when I worry too much about my DH being away (or just working extra late, which he will be tomorrow and I'm already worried about THAT, let alone 4 days!), it just gets worse. Like, just give in to the mess and absurdity of it all. Just today, I was feeling like crap, and there was still a full 6 hours of time before Dh came home. I got into bed with a load of books and read, then dozed off with them. Best wishes to you. Before you know it, your DH will be home.
