To say the truth it's a challenging but rewarding experience. I only can give some advices: spend time with your child, encourage your child's independence. Don't fotrget about clear expectations and boundaries. Children at this age are starting to learn about rules and consequences. And just love!
I sugest for more learning activities... A child of this age should start practise painting, learning math... Try some sites, for examle go to https://wunderkiddy.com/category/3-4-years. Here some worksheets for kids
