*Hugs* Being overtired makes everything that much worse doesn't it? Maybe going back to work will be a turning point for you as well. I do find that even though I have worked a full day I am so excited to get home to my kids that I actually have more patience than when I was home on leave with them. I think I am more relaxed during his night routine now which helps him relax a little more. Of course, even as I write this we had a tough night tonight with him so we are by no means in the clear yet. He took a catnap tonight from 5:40-6:30 and then down to bed at 8:15, but he woke back up at 9:15 and never really recovered until 12:00 am. This is the trouble we used to have and I can pinpoint it to a day of bad naps while at daycare. That part is frustrating because you can't control what happens with the sitter. But either way, I think I can go with it easier because I got that break during the day.
Keep us posted on how things are going!
