When child 3 was born, child 1 was four years and three months, and child 2 was two and a half, exactly. Dh was active duty military and deployed to a combat zone (Iraq in 2004) when child 3 was three weeks old. He was gone for six months and we were fortunate to be able to talk on the video phone a few times each week, except for a few periods with heightened security; during the battle of Felujah we had zero communication for three weeks.
I was a SAHM. After dh left, I hired a cleaning lady to come every other week. Older two children went to preschool 3 hours a day, five days per week.
