Sometimes children were not baptised for years...and then three or more baptised at the same time. I've come across children left of censuses until someone was present at time of Electoral calling to take names in property. Similarly, some families waited until they thought the family was complete before getting them baptised and entered into the Church Registers, especially if they lived in a remote residence, away from towns and villages. Even their day, month and year of births could be vague upon giving the information to the official taking the details.
