hello, my baby is now 15 months old. he used to walk on his own. but because of fear of his falling down, we used to hold his hand everytime while walking. suddenly one day, he started getting frightened of walking independently. If we left his hand, he got scared and put down his hands on ground for support, as if he is going to fall now. I did not understand what made him change like this. Babies have fear initially, but later thry they get confidence. My baby was confident first and now he has got fear. please guide me, how to correct this.
