I bring him to playgroup 2 times a wk....also bring him to the park nearby to play, he enjoyed a lot esp when i bring the ball so he can hold the ball and walking on the grass.
Besides, play the toys at home and turn on the music, teach him to dance. Same as other bbs, he loves to 掃走疊好的積木 instead of building them up. He starts to interest to roll the car.
