We know that small children, including infants, were present when people gathered as a congregation in biblical times; for example, in Deuteronomy 29, Moses gathered all the people of Israel and addressed them. In verses 10-11 we read
10 Ye stand this day all of you before the LORD your God; your captains of your tribes, your elders, and your officers, with all the men of Israel, 11 Your little ones, your wives, and thy stranger that is in thy camp, from the hewer of thy wood unto the drawer of thy water: (KJV)
What did people do with children in such gatherings? Being children, they would have made noises. Were there olden-day equivalents to the creche or crying rooms? Or were the adults, especially the leader, simply more tolerant towards children than people in religious gatherings are today? Can we know this from the text such as Deuteronomy 29:10-11?
I am interested especially with the case of very young children, i.e. three years old and under.
