Finally Joshua can ride tricycle

Finally, Josh can pedal his tricycle today. I bent down to hold his foot and keep reminding his leg to be straight for 3 rounds until my neck ache. I almost give up and finally when I almost can not control my temper, he can pedal it in the correct manner. I read back this post, it took him 3 months to be able to pedal his tricycle. I admit that today could be my fifth time to bring him to playground riding the tricycle. A few times before I want him to ride, he refused. But my helper bring him down ride tricycle every day.
