I allocate my time so that I know what is time for me and DS, and what is time for housework - otherwise I end up doing both incredibly halfheartedly! Our daily routine is generally:
7.30 out of bed and dressed (have to get ready before DH leaves for work otherwise I'll slob around in PJ's all day and get nothing done!)
8.00 breakfast for DS, coffee for me
8.30 DS has around 30 mins tv time while I get on with housework
9.00 playtime with DS - I may set him up with something to play with eg crayons, some toys etc or I may sit and play with him depending on what we have planned later in the day.
10.00 story time, quiet down gradually for naptime
10.30 nap for 2 hours. I spend half of this time doing jobs and half relaxing as its my equivalent of a lunch break 
12.30 lunch for DS
Afternoons we always go out unless there's a very good reason eg illness. Varies between baby groups, meeting friends for coffee, or simply going the supermarket and jobs in town.
5.00 tea for DS followed by 30 mins of tv
6.00 bedtime wind-down, story, milk, cuddles etc
6.45 bedtime.
I try to prep everything for tea when DS has his nap so it's easy to make once he's asleep. I tend to make things which will be nice reheated for DS the following day so I'm not cooking twice, but DH doesnt get home til 6ish which is too late for us all to eat together. Obviously some days this all falls apart, but I try to stick to it as it feels like the right balance between housewife and DS enjoying himself!
