My DS is 4 weeks old. So far, this is what he's doing (and I'm following):
Between 6am and 8am: Wake up, change nappy, feed. DH leaves by 7.30am.
DS will sometimes go to sleep until 10am-ish. Even if he's not asleep, he's generally still calm and contented, so I put him in the moses basket and take it into the bathroom while I shower etc. Then I get some breakfast.
Morning: Sit on sofa, feed, talk to him, see if he'll sleep (usually he just wants to feed, today he dropped off at 11.30am, yay!).
At some point, I might go out in the buggy, when he'll generally drop off for a while.
Lunch: Got when I can. Today he was asleep, yesterday I ate one-handed while I fed him.
Afternoon: Like the morning! I'm more likely to go out in the afternoon, and he is more likely to have a long sleep, but that's completely unpredictable.
If I need to get dinner/do stuff, I put him in the sling. He generally drops off to sleep eventually (after some protesting).
6pm ish - DH comes home and takes him for a while. If he's crying, DH will take him out in the sling for half an hour or so.
We try to eat dinner with DS in his bouncy chair. However, more often than not, he starts crying and wanting to be fed or entertained.
Evening - Cluster feeding until 8pm ish. Then bath, feed and try to get him to sleep. This can take a while! He will then sleep through, waking once for a feed and going straight back to sleep.
Night-times seems to be fairly predictable, but the daytimes are not at all. On Saturday, he was awake almost constantly from 9:30am until 9:30pm. I'd say a sling is your friend!
