Many families today are not "typical." Children as a result can extensively interact with many siblings, extended families, friends, and/or neighbors. All of these interactions can have a huge impact on how secure the child feels. For example, if the child is constantly competing with these other people for attention, he may feel less secure. On the other hand, if there is always someone there to interact with the child, or someone who can play the role of "mom" then the child is likely to feel more secure.

I agree that family dynamics can greatly affect security and attachment. If one has an older sibling who is particularly responsible, they may take on the role of a "secondary mother," possibly creating more attachment to him/her and less dependency on the mother.
