I’m in the fortunate position of being able to put my 2 year old into nursery on my day off, for some of the day.
I work 4 days. DC spends 2 days with my mum, 2 days at nursery.
Sometimes on my day off, I put DC in nursery for a half day or a “school day” (ie short day) to enable myself to get chores done or exercise. And also I admit I find a full day 6am-7pm with a toddler stressful 
Then I spend the rest of the day doing something fun with DC.
Some weeks we do a day trip so DC is with me all day.
I feel so guilty, even though DC loves nursery and the most DC is ever at nursery is 3 days per week.
I was wondering if anyone else does this, or if you would it if were an option? (Realise childcare expensive so this is not an option for many, and realise I am fortunate to have the choice)
