I work 2.5 days a week, usually Thurs-Sat, so a usual week would be:
Monday: trip to soft play / play Barn with lunch there, home to nap, play at home, eat dinner together 5:30 when DH gets in, 6:30 bath and night garden, 7:30 bed
Tues: same as Monday, but morning is a trip to a church hall playgroup to meet a friend or two, lunch at home.
Weds: same as Mon, but morning is mini gymnastics session at the local leisure centre, trip to the park, lunch at home.
Thurs: nursery
Fri: nursery
Sat: morning out with DH, usually soft play and lunch, home to nap, afternoon trip to the park maybe and sometimes dinner out.
Sun: family day, whatever we fancy!
In Sept I go on Mat leave, so I'm switching his nursery days to the start of the week. Thurs & Fri I have friends from my NCT class that meet up, so we'll do outings with them on a morning and he can have some mad toddler time whilst I have the new one to focus on!
It sounds like you're doing lots, but I know where you're coming from, I always worry that we're not doing enough, or I should be finding more educational activities to do, but they do learn a lot just by being around you and doing normal person things
