We see nothing in the New Testament Bible to suggest Jesus taught that children should remain silent. The character of love and compassion that Jesus displayed would suggest that He understood they needed to laugh, play, sing and would never have taught they should be confined to silence.

This is what we know about Jesus with regards to children:

Jesus loved children. At one time some children wanted to come to Him and the disciples (Jesus’s close followers) rebuked them and turned them away. 

Jesus said this of children in the New Testament Gospel of Mark:

“Let the little children come to Me, and do not forbid them; for of such is the kingdom of God.” (Mark 10:14, NKJV). 

In the New Testament Gospel of Matthew, Jesus said this of children:

“Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven.

Therefore whoever humbles himself as this little child is the greatest in the kindom of heaven.

And whoever receives one little child like this in My name receives me” (Matthew 18: 3, 4, 5, NKJV). 

When Jesus healed Jairus’s daughter, and brought her back to life when she was dead, He immediately asked for food for her. He loves children and cares for them deeply.
