First time alone during witching hour - how can I manage?

We have twin boys, they are 3 weeks adjusted, 10 weeks actual. My husband had to go out of town and of course the witching hour has been the worse since he left. It breaks my heart when I cannot console both at the same time, I am terrified picking them up both at the same time, even though I moved to the floor on a mattress.

What do you do in these scenarios? How do you deal with the emotional difficulty of having one cry while consoling the other? Also, how long is this till they are over the witching hour stuff:S?

I was also wondering...this happens more when we get out for a walk or there is more stimulation the second half of the day. It gives me so much anxiety that we spend most of the day in a darkish room and they are mostly avoiding that witching hour then.

Yesterday I ventured out with them around 7 pm, as I have to somehow walk our dog, so packed them up in the stroller and went. They did not sleep just looked around and the night after was pretty bad. They ve been fussy with every feed, while usually they just sleep into it and go right back to their cribs to sleep without much fussing.

I am considering just not stimulating them much, but am I messing their development up like this? How would I know when to expose them to more stimulation? This is all so difficult. HELP!
