>>40966745I was always playing pokemon, toys and games. My older sister who is about 6 years older was obsessed so i had all the merch and current games out the gate. I'd say give ur child some plushies, and toys later on (about 3 years old) and get them to watch the anime every saturday morning or whenever it's on. When starting school try have it on the TV when eating breakfast. If you want them to like pokemon when they are older make sure to be involved by watching anime, playing the new games with them, and general discussion. It's all up to how you live ur life though but it can never be too early.
Also tip make sure they don't feel embarrassed about liking it when they are a young teen, i remember a phase where everyone made fun of each other for liking it bu then when reaching late teens everyone loved it again.
