The first verse of Chapter 6 is set when Mary is six months old. Anna sets her down on the ground to test if she can stand. Mary takes seven steps and comes back to her mother. Anna picks her up, declaring that Mary will not walk on the ground again until she has been brought into the temple.
Anna makes a sanctuary in her bedroom and allows nothing common or unclean to be brought into it. I'm going to assume 'her bedroom' is Mary's, and not Anna's. :) The last line is interesting: 'And she called the undefiled daughters of the Hebrews, and they played with her.' The note is what I find interesting, 'The Greek verb here is ambivalent; it might be translated "diverted." It could also mean that the girls "led her aside," a euphemism indicating that they took care of her toilet training. Elijah uses it when he mocks the priests of Baal, whose god is ignoring their supplications: "Cry aloud...; either he is musing, or he has gone aside" (1 Kings 18:27).' So either the neighborhood girls were allowed to come and play with Mary or they were tasked with her toilet training. It's a bit of a difference... :)
The second and third verses of this chapter take place on Mary's first birthday. Joachim throws a huge feast, inviting all the priests, scribes, elders and people of Israel. Surely not *all* the people. Probably just a large number of people that he knew. The priests and the people all bless little Mary and then Anna takes her back to her sanctuary-bedroom. So in that respect it's just like every other first birthday party. The kid's too little to really care and gets tired and goes down for a nap while the adults have fun. Nice to know nothing has really changed.
One last thing, while Anna is breast feeding Mary, putting her down for the night, she sings a song to God: 'I will sing a hymn unto the Lord my God, for he has looked upon me and taken away from me the reproach of my enemies. He has given me the fruit of his righteousness, unique and yet abundant. Who will announce to the children of Reuben that Anna is nursing a baby? Hear, hear, you twelve tribes of Israel: Anna is nursing a baby!'
