I only partially know where you are coming from, as I am a stay at home mom. I don't know how working moms do it. I don't know if any of these things will work for you, but they are things we have done that work.
First and foremost, talk to your husband. Tell him everything and that you really need some help. Try to do it like you need him, not like nagging. I was able to do most of the work when it was just 2 kids, but now that we have 3...his help is a MUST! Don't get me wrong, sometimes I get mad at him and we have a little spat, but it gets resolved and he helps out. Seems like once in awhile they need a reminder. Also, I will give him a choice...like after dinner, I will say "Kids or Kitchen?" and he picks. Sort of like giving kids a choice...makes them feel in control.
Sounds like the sleep schedule is pretty good. I would just try to get the oldest to go to bed at the same time (9pm) as the others. Thats what we do here...and then I get the time after that as my quiet time to do whatever I need (usually involves a glass of wine...lol). It can be done...my son was a night owl too...but once school started, we had to change our schedule. My son also used to always sleep with us, but when we moved to our new house, the 2 oldest(at the time, 5 and 2 Boy & Girl)began to share a room. Seems like if they have someone with them, they sleep better. Got a night lamp and cd player with bedtime music, and it worked wonders! Our sleep schedule is 9pm for all the kids (7yrs, 4 yrs, and 6 mos.)We all are awake between 7 and 8am.
You could also try sticker/reward charts (works for some...not all). Could do it for both sleeping in own bed, and for picking up. My kids earn a sticker for each good thing they do, like helping unload the dryer, or picking up toys. My 7 year old has to earn 6 before getting a prize, my 4 yr old needs 4. If they fill the whole chart up (which is about 7-8 rows), they get to go to chuck-e cheese. The prizes for single rows can be anything from playing a game with mom, reading so many books, or a toy from the prize box(dollar tree rocks!)etc. This helped me a lot because like you, I didn't feel like I had the time to just sit and play. So, as mean as it sounds, they earned my time. Then we both won. They got me to play with, and I got the house picked up.
As good as it all sounds...I am still tired at the end of the day, and don't have much time for myself. My hubby doesn't get lucky real often, but he understands. I figure the me time will come when I get the kids all off to school. I know that sounds like FOREVER, but it goes by so fast. I can't believe my middle child will start preschool in the fall (late bday). Hang in there and talk with your hubby. I hope you can find something that works for you! Good luck!
