2.14-Jesus believed that God had created humans as male and female.  They could come together in love and form a family and children would be brought into this world as the greatest gift of all.  Jesus loved the family and loved the children.  He wanted them to be welcomed.  He didn't want the children hindered.

Genesis 1. 

²⁷ God created man in His own image, in the image of God He created him; male and female He created them. ²⁸ God blessed them; and God said to them, “Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the ^[al]sky and over every living thing that ^[am]moves on the earth.”

Matthew
19.

19 When Jesus had finished these words, He departed from Galilee and came into the region of Judea beyond the Jordan; ² and ^[a]large crowds followed Him, and He healed them there.

³ Some Pharisees came to ^[b]Jesus, testing Him and asking, “Is it lawful for a man to ^[c]divorce his wife for any reason at all?” ⁴ And He answered and said, “Have you not read that He who created them from the beginning made them male and female, ⁵ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’? ⁶ So they are no longer two, but one flesh. What therefore God has joined together, let no man separate.” ⁷ They *said to Him, “Why then did Moses command to give her a certificate of divorce and send her away?” ⁸ He *said to them, “Because of your hardness of heart Moses permitted you to ^[d]divorce your wives; but from the beginning it has not been this way. ⁹ And I say to you, whoever ^[e]divorces his wife, except for ^[f]immorality, and marries another woman ^[g]commits adultery^[h].”
¹⁰ The disciples *said to Him, “If the relationship of the man with his wife is like this, it is better not to marry.” ¹¹ But He said to them, “Not all men can accept this statement, but only those to whom it has been given. ¹² For there are eunuchs who were born that way from their mother’s womb; and there are eunuchs who were made eunuchs by men; and there are also eunuchs who made themselves eunuchs for the sake of the kingdom of heaven. He who is able to accept this, let him accept it.”

Jesus Blesses Little Children

¹³ Then some children were brought to Him so that He might lay His hands on them and pray; and the disciples rebuked them. ¹⁴ But Jesus said, “^[i]Let the children alone, and do not hinder them from coming to Me; for the kingdom of heaven belongs to such as these.” ¹⁵ After laying His hands on them, He departed from there.
