We don't have a typical day either but it sort of goes a bit like this.
6.30am or 8am, DH leaves for work.
8am ish, DD wakes up. If DS is still asleep, go into DD and read, chat to her, give her some juice, make myself some tea. If DS still asleep, get DD dressed. But if DS is awake when DD wakes up, then I feed him while trying to persuade DD to sit in bed reading for a bit and drinking her juice.
Once DS is fed, changed and conked out again, and DD is dressed, I put Charlie and Lola or another 10 min programme on iPlayer on my iPhone for DD while I have my shower and get dressed. After that DS hopefully stays asleep upstairs while DD and I go down for brek. I stick in a wash at this time.
One morning a week we go out to toddlers in the morning. Another morning my parents come round to collect DD for the day so we all have coffee when they come. Probably another day we go out for lunch to my friend's in the next town.
At some point DS wakes up so I feed him again and change, while trying to persuade DD to play with her toys or if that fails sticking the TV on for a bit!
We have lunch at whatever time it looks like it will work - ie when DS is fed, changed and asleep again. Then DD plays a bit more and, while DS is still asleep, I try to tidy away the lunch things and get a stew/bolognese/something similar, on the go for supper later on. If DS obliges by staying asleep long enough DD and I hang out that mornings wash and put away the stuff that has dried.
Then DS prob wakes and I feed and change. DD is getting tired so prob the TV goes on again for 20 mins.
Then its 2.30 ish and if we haven't yet been out, I load them in the car and go out for a bit of a drive and a walk/fresh air. DD's only 2.5 but since turning 2 won't nap except in the car. So she has 20 mins sleep while we drive about, DS is asleep. I listen to my iPod and eat a Mars Bar! Then we have a little walk / go on playground and then head home.
When we get home I feed DS and change him and put him in his chair or mat.
DD watches TV from 5.30 while I get her supper ready. She eats at 6 and we go up for a bath at 6.45. DS is much more awake at this time so I am often feeding him while she eats/ is in the bath etc. Or he is in the sling or in his basket with his dummy! While DD is in the bath I get her to sing a song (so I know she isn't drowning!) while I run up and tidy up her room after the days shenanigans.
DH gets home 7.30pm. If DS is asleep, he prob gets in the bath with DD, then I get her out and do story and bedtime. If DS is awake, DH takes him while I do DD's story.
DD is asleep by 8 and hopefully by the time I get downstairs DH has settled DS in his basket with his dummy. DH finishes off prepping our supper which I have probably started earlier in the day.
We eat about 8.30 and watch TV, with wine 
At some point DS will wake up and not want his dummy anymore but want booby instead. It tends to be around my bedtime anyway, so at that pointy I head upstairs, feed and change him and we go to sleep. He is in my bed, DH in the spare room.
Generally DS sleeps pretty well and having been fed at say 11 will wake again at 3 and then in the morning between 7 and 8, say. Thanks goodness DD sleeps through pretty much reliably, though with the shock of DS' arrival she does sometimes regress a bit, including one nightmare night two days ago when she was crying for me to sit with her between 2 and 4am solidly, together of course with DS being desperate for a feed. Two screaming children in the early hours of the morning was NOT fun 
!
Yawn! Right now DD is doing stickers at the table, DS is asleep and it is really calm. But soon I know she will be having a tantrum and he will be screaming for a feed!
Then it all starts again!
