S.O.
The only tip I can give going from a 2-parent home to a 1-parent home is to still treat things as if hubby were there. My husband is in the Navy and, up until shore duty, was gone often. One of things we did was have him read stories and record them to VHS. Another thing we did was set up webcams. We'd try to make it a daily thing where we'd chat by instant messenger and use the webcams. It helped things stay as normal as possible. Hope my ideas help.
A little about me, I am a SAHM to a 13-year-old and a 5-year-old. I have been married to my high school sweetheart for more than 13 years. I am trying right now to return to the world of work. Here's to hoping.
