Maybe. Maybe not.
The most common “start” to childhood memories beginning is a major life change in early childhood. Modernly (last century or so), in 1st world countries, that meant the overwhelming majority memories “start” at around age 5 when they started kindegarten. As the necessity & desire for dual income households has blurred that line? (Daycare, preschool, elementary school) Those numbers are changing.
Various sub-cultures in 1st world countries childhood memories tend to start much earlier, and much later. Military brats usually begin episodic memory around age 1.5-3yo (their first major move), and sometimes linear memory. Abused kids tend to not recall much before their teenage years, and many not until they leave home. Religious enclaves (think Amish, not cults) usually begin at around what Catholics call 1st Communion… anywhere from age 5-12 depending on the enclave… when a child takes on more responsibility in the community. <<< All the examples I know of (and I know a lot worldwide, several score) follow the general rule that SOMETHING big has to change to interrupt the “how it’s always been”, to kickstart a new way of recorded memory; and it usually follows an independence-seeking-time, neurologically. Toddlers. 5/6yos. Puberty. Teens. Young adults.
There’s no known way to recall memories from before that changeover happens UNLESS it’s traumatic-amnesia rather than memory not encoding the way it does after change (in a way that we can consciously access).
So, IME, whether you get memories from before your illness with your mom or not? Would depend on if you’re talking about the normal/natural way we record memory, (in which case, at this time, there’s no known way to access earlier memory); or if there’s a traumatic lock on those earlier memories (in which case, yes, there are numerous ways that people start recalling traumatic pasts).
