Hi Emma, hope I cover everything with my reply.

Day sleeps DS will feed to sleep, like he does at night. Otherwise he will go to sleep in his pushchair or strapped to me as I walk around. We co-sleep, but he always has his first sleep in his bed because when he sleeps through I don't want to then change things. DS has 3-4 day sleeps, but they are all short sleeps, about half an hour each.

Our routine, well, we fell into this because of what suited my coffee mornings, so it is as follows:

7-7.30 get out of bed. Get up, dressed, breakfasted, ready to go out. If DS has been awake since 6ish, he has a sleep about 8ish.
9.30ish go out for a walk. Mornings are mummy-time so we play quiet games. Quite often DS will fall asleep before 10.
12.30ish he's asleep for my lunch. He wakes up and we share some fruit.
Afternoon nap is unpredictable, but afternoons are full of songs, dances, stories, games, hugs - it's full-on DS time now he has had a chance to do things for himself.
4.15 car-watching (DS loves watching cars go past)
4.30 DH arrives home, quick cuddle
5.30 Boys play-time while Mummy makes dinner
6.15ish Family Dinner (we each have our own food and it's sociable at the table, more to teach DS about social meals than about him eating right now, although DH and I do feed him).
7 start of bedtime
7.45 usually in bed asleep.

So that's the rhythm of our day, it can change a bit but DS likes knowing what's coming next and it fits in us going out and his playgroup (which is in the afternoon). Maybe if you write it down for a few days you will see a pattern emerge that you can encourage.
