I work part time in the evenings as well. My schedule varies, sometimes I am home by 8, 10:30 and there will be an occasional midnight. It has been a big adjustment for us as well. I am utitlizing my crockpot more, I don't get up with hubby (just give him a kiss as he leaves), my kids are 10 and 11 so they let me sleep in. The latest I can sleep has been 9. I try to get school going by 9:30 or 10. Making a meal plan has been helpful and I try to get all the prep done for hubby. We try to eat supper together but sometimes I need to leave the house by 4, so they eat and I eat when I get home. I take a 20 minute power nap almost every day. It's my sanity saver. Not getting enough sleep is hard but the naps do help! I usually do it during the kids daily reading/quiet time.
Most days we get all the school work done. Making a list for the kids has been helpful. They just check it off while they go. On days where I feel more rested, we attack the extras and get them done. I tell the kids that this is a busy season for our family, we just have to work together to get it all done and do the best we can! good luck
