Attitude Adjustment

In the last week, I've noticed a shift in my mood and attitude. I printed some motivational art and hung it on my refrigerator. My 5-year-old daughter wanted to know what it was and why it was in her usual art spot. I told her it was a reminder that everything will be okay. She smiled and said that was good. She doesn't seem to mind it taking the place of her latest drawing. She's a good kid like that.
 I've decided to just "go with the flow." This is not something I am accustomed to doing, but I'm giving it a shot. My version includes eating a lot of sugar, I'm not sure if that's a good thing though.
 I've also decided to try doing P365+1, or whatever it's called. I recently added Instagram to my phone and have been trying to take 1 picture a day with it. If you're one of the few people who follow me, I apologize for my randomness, but that's just me. We're still moving right along with our fence building, which is probably why half of my pics are fence related. (see pics above)
My children have even noticed a change in me. This weekend, my 7-year-old son asked me why I wasn't so "RAWR!" anymore. Yes, he really did ask me that, complete with claws. I guess I had been more stressed than I thought. Tonight, after I had cooked a full dinner, complete with a vegetable not dumped out of a can, my son told me I was his "favorite parent" and my daughter agreed and said, "Daddy is the worst!" If you had been here a month ago, you would know how unreal this all seems to me. The 3-year-old is the only one who acted as if she even liked me and that was just because she was with me all the time and had no choice. I'm not sure I want to take over the role of "fun parent," but it might be nice to have some goodwill going into summer vacation. After all, it looks like we're going to be spending a lot of time together.
I've been jotting down ideas of things to do this summer. Keeping 3 children occupied every day is going to be a challenge. I've seen a few Pinterest lists and have been thinking about copying some of their ideas. I think it might do us all some good to have some kind of "schedule,"so we're not all at a loss and totally bored every day. I'm trying to incorporate all the things they like to do. You know, some video games, some science experiments, some reading, a lot of playing outside, some crafty stuff, etc. Hopefully, I'll remember to take lots of pictures and squeeze in some scrapping time.
I want them to have a fun summer like the ones I remember having. I liked spending a lot of time outside and reading. I might have been kind of boring though. I don't want my kids to dread summer vacation. Any ideas of fun things to do with an almost 8-year-old, almost 6-year-old and a 3-year old? What did you like to do when you were a kid on summer break? I could really use some ideas.
