My kids are 2 and 4 and we don't have a rigid schedule but we do more or less have a schedule, it looks sorta like this...
wake up until lunch time...we eat breakfast and then sometimes I go and work out and they go to the daycare. This is also the time we see our friends, go to activities around town, libraries, hit the park, etc. It's basically the meat of our day. Sometimes if we are out and about it leaks into lunchtime and we have a picnic or eat out.
This is also the time I use to go to the grocery store and run errands. I don't do that every day of course, so on those days I try to do something for them and something for me.
Lunchtime +
After lunch my kids rest. My 2 y/o still naps but my 4 y/o doesn't. Regardless they both go to their rooms for at least an hour and play quietly, read, lay in their bed, etc. Usually my 4 y/o gets so wrapped up in what she's doing she'll stay in there for over an hour and sometimes make it to 2 hours! Woo hoo!
During this time I do laundry, clean, catch up on emails and sometimes I just sit down for an hour and watch a little TV.
Afternoon-evening
Usually we just hang out. This is the time my kids are allowed to watch a little TV so they usually do. We also play outside in our yard or take a walk. They have time to play while I make dinner. We eat kinda late so after dinner we usually wrap up and get ready for bed.
Since it's summer we usually go to the pool in the late afternoon and stay for a couple of hours. I take all our shower stuff and give my kids a bath. For dinner that night I make sure it's something that is already mostly cooked so that we can eat right when we get home. We usually do this at least 2-3 times per week during the summer.
