We have a very solid routine here with me, SAHM and 3.5 yo DS. DH works a regular schedule--gone from 7:30 to 5, give or take.
6:30 Wake up, make beds (DS sleeps in toddler bed in our room). DS gets himself dressed and brushes his teeth while DH gets ready for work--I start breakfast and pack DH's lunch.
7:30 DH leaves for work, DS and I eat breakfast. I do dishes (after he clears his place) while he plays in playroom--open to our kitchen.
8:30 I get myself showered/dressed while DS plays in our room.
9:00 or 9:30 we head out for the morning. Gymnastics, farm pickups, shopping, playground, long walk, etc.
11:00 Back home to make lunch, eat lunch, clean up lunch
12:00 or 12:30 upstairs to our room for rest time. First I read to him for 20 minutes or so, then he plays by himself (sitting, quietly!) for 40 minutes--sometimes listens to book on CD. I read in bed.
1:00 or 1:30 Housework time. I clean/do laundry while he helps or plays by himself (usually a combo of both).
2:30 ish we do one of the following: play outside at our house, go to a close-by playground (if we didn't in the morning), or stay in and play games, do puzzles, etc. If I am worn out by then I read in a chair in our driveway or on bench at the playground while he plays outside, or on the couch in the playroom while he plays.
3:30 or 4:00 Bath time, he gets his PJs
4:30 I start dinner--he helps or plays in his playroom.
5:00 DH gets home, we eat dinner, I do dishes while they play after dinner.
6:00 We all go upstairs for DS' bedtime (with no nap he is asleep by 7!) We have a very solid routine: last pee, DH does his toothbrushing and flossing. They meet me on the "big bed" for a story or two, then he gets into his bed--we talk about our day (listing what we've done and each one of us picks our favorite part), then we sing to DS for a few minutes. After hugs and kisses, DH leaves the room, but lately I have gone back to staying with him due to nighttime fears (he was fine to fall asleep alone from 3-3.5). I read by lantern in the big bed while he falls asleep a few feet away in his bed--it takes about 15-20 minutes usually.
I love our rhythm, and it makes DS so calm and well-behaved to know what is coming and how everything is done! He's much more likely to get fussy or throw tantrums when we have no schedule or we're outside of our rhythm!
