I'm not sure that a person would write how old a picture is as an age. If you were trying to record a date that you sent a card or a letter, you'd think that they would put the current date down.
The children, could one be 1 year old, and the other 1 year 5 months old? I know it seems like a biological impossibility but they could have been from two marriages, or adopted.
Ignoring what's already been written, how old do both the children look?
