I would definately walk that three times a day, you're soooo lazy.
7.50-8.30 Walk in with three kids so give youngest a toy and quiz eldest two on maths, English, science.
8.50-9.30 Walk back with baby so practice speech and counting.
90 minutes to change, feed toddler, change the bed sheets, hoover the down stairs
11.00-11.40 Walk in with baby, learn to name nature
12.00-12.40 Walk back with two, get middle child to teach baby all she learnt that day
2 hours to feed kids, hoover upstairs, swap the washing over, clean the bathrooms
14.40-15.20 Walk back with two, make up poems about the route
15.30-16.10 Walk back with three. Get oldest to teach middle child everything she's learnt that day.
Then two hours before DH is home to do home work, cook dinner, clean kitchen and living room. Honestly if you're not doing at least this every day you're wasting your life.
I only live a mile away, we occasionally get the bus and sometimes I use the three hours at nursery just to drink coffee but you know, if I lived your life I'd TOTALLY walk it all 😉
