A child is a young boy or girl in the care of parents, older than a suckling or an infant, but not yet an adolescent. "Children" are sometimes used as a name for a large group of descendants of one person, such as the Children of Israel, or even all human beings as the Children of Men. A child represents innocence and charity, where innocence is the willingness to be led, and charity is love. This is why Jesus blessed them and suggested that we all become like children in order to enter heaven.

2780. 'In the morning Abraham rose up early' means a state of peace and innocence. This is clear from the meaning of 'in the morning', also of 'rising up in the early morning', when used in reference to the Lord, who is 'Abraham' here. 'The morning' in the universal sense means the Lord, and from this His kingdom. Consequently it means the celestial element of love in general and in particular, as shown in 2333. And as it means those things it means the state itself in which they exist, which state is one of peace and innocence. The state of peace in heaven is like that at dawn on earth. Within the state of peace in heaven all celestial and spiritual things manifest themselves, and from it they derive all their bliss, blessedness, and happiness, even as at dawn on earth when all things present themselves to man with a delightful and gladsome air, for each specific celestial or spiritual thing receives its character from the general affection, 920, 2384. The same applies to the state of innocence. This manifests itself within the state of peace and is something general and overall which brings itself to bear on all things of love and faith. Unless the latter possess innocence within them they lack their essential element. It is for this reason that nobody is able to enter heaven unless he possesses a measure of innocence, Mark 10:15. From this it is evident what 'in the morning' means in the internal sense, even more what is meant by the words 'in the morning he rose up early'. And since in the highest sense 'the morning' is the Lord, and He is the author of the state which brings into being and exerts an influence on the things that exist in His kingdom, 'in the morning' and 'rising up in the morning' also mean further things still which arise in that state and are related to the things that follow in the internal sense.
