Hi E.,
I was in the military and I got out when pregnant with my youngest. So I've been through the transition. Fortunately my hubby got a great job right out of the military and that along with my pension allows me to stay at home with the kids.
I actually feel that our days work out better if I don't make a super structured schedule. We eat breakfast when we get up. We eat lunch when we're all hungry etc... it works for us. Yes it's mostly about the same time each day, but I'm not going to freak out if we have lunch an hour later than usual on one day and dinner earlier on the next.
I try not to plan anything for greater than a week or two ahead of time. I do like to keep our days flexible so if my kids say "Hey, can we do this or that tomorrow?" I can usually say, "Sure, why not!" :) We have a lot more fun together this way since it's a bit more spontaneous.
Don't forget to stay at home and relax every once in a while. That's important too. Take one day every so often and just give yourself the day off. No housework, only food prep. Catch up the next day.
Find something you love to do and do it as often as you can. I love to cook new things, so I try a new recipe on a regular basis and have come across some great ones. It's fun to plan it out and shop for it. Maybe you could pick up a hobby you've always wanted to try. I picked crochet back up when I finally got to stay at home and I've been doing a little bit of sewing too. Crafting, especially when it's something useful around the house, will make you feel very useful and clever! :)
As for my relationship, it's never been better (and it wasn't that bad to begin with! lol!). I have the time to nap with my little one in the middle of the day if I want, so I have the energy for my hubby when he gets home from work. I can also stay up later now since I don't have to get up until we all "fall awake" in the morning, so I can put the little one to bed then put my hubby to bed, then do school-work with my older son before sending him to bed and still have an hour or two to myself at night after they're all asleep and my nightly chores (make hubby's lunch, iron his pants, do the dinner dishes etc..) are done. Make sure you find a way to work in that time for yourself.
Of course, we homeschool so we're not subject to a school's schedule and you are so you may need to take a more structured approach.
Best of luck to you though. Message me if you ever just need to chat with another grown-up. lol!
