However - do be aware of overtiredness/overstimulation. It is a tricky line to walk.
When they start walking they need more food, more drinks and more sleep while they adjust to the greater expenditure of energy. He will need a nap in the afternoon for about 2 hours as well as at least 10 hours at night. If he doesn't sleep well at night he will need a short nap and a long nap during the day.
Routine is everything at this age. Toddlers need to know what is coming next. They have a short attention span so need very simple updates frequently. Also, they are not good with choices so don't ask what they want to do, just say we are going to the shops/park/whatever, then we will have lunch (for example).
I think it helps if you completely lower your expectations of getting much done. If I managed to get one load of shopping, or one wash load done in a day I was glad.
It is worth focusing on them because they are calmer, sleep better, and you can get things done while they are asleep.
They love to "help" at this age too, so unpacking shopping, sorting laundry, tidying shoes, putting things in pairs etc make them really happy.
