Your feelings are valid regardless, but some food for thought- memories are easily rearranged, they're not static, nor unchangable. Examining memories in therapy can really make them vulnerable to confabulation. The typical age of the first retained memories that most adults can access is between four and five years old (and varies based on gender, culture and other factors.) While it's technically possible to have earlier memories (and that younger age limit does trend down into the late 3s in some cases) it's equally or more likely that what *feel* like preverbal "emotional" memories are rather feelings exacerbated by therapy- when we feel extremely vulnerable, its easy to translate that as infant-like feelings, when they're not necessarily that. And in highly emotional states, memory is often compromised more than usual. (Think of the classic car crash scenario where so many witnesses don't recall the basic details like color of the car.)

This isn't to discount your feelings, but to give you a little context as far as the possible source.
