You can start by homeschooling your child now. Read to him, buy activity books, play card games. Or you can even search on Instagram for kids activities etc
Can read some books, play some toys like Lego, playdoh, and sing some songs. Do include 30min of outdoor play/walk too.
U can follow adams playtime at ig for inspiration. Otherwise, try sensory plays. With rice grains, beans, dough, sand..
