People ask if my boys (18 mo apart) are twins all the time!
Pictures of my husband and Little Guy at the same age could be mistaken for each other, if not for the clothing/photo quality.
There are 8 grandchildren on my mom's side. You can start at one end and trace resemblances through each of us in a connect-the-dots pattern.
Our genes run deep :)
Do you have strong family resemblance? Among you and your siblings? yourself/spouse and your children? your children? Does it extend farther to cousins or across generations?
