Found out i am pregnant.

I just found out that me and my husband are pregnant. We just had a baby October 2016 so we are nervous how this is going to go. I am also trying to figure out a way to tell my mother as well that I am pregnant. This will be my fourth child. Together that will make 8 but only 4 that live in the house 5 if you include the lil peanut. Has anyone had children back to back and how was it.
