This is perfectly normal behavior for lots of children. But being closer to your age group, my parents were of the same generation and also have spoken about this type of behavior as "difficult". At the time spirited, active and independent kids were considered difficult and parents used corporal punishment to keep them in line. My parents weren't abusive either but when they'd talk about my older brothers behaviors (both are about 10 - 13 years older than me) and how they handled them, it's a little shocking. My mom still blames us as babies for how they responded to us. We were all difficult either by being overly demanding or under demanding (or rejecting) babies. To this day she is very defensive and took our infant bahavior very personally. We had countless debates regarding holding and giving newborns too much attention. Everything she tried to teach me went against my basic instinct as a parent. Identifying the infants needs and responding to them is a parent's job. It's very apparent to me now how her perceptions and reactions to us definitely shaped the way we attached or failed to attach. Not to the extremes of a child with reactive attachment disorder by any means. But still, enough to contribute to the development of dysfunctional personality traits in one way or another.
