A little late, and it relies on a lot of "ifs" seeing as she isn't a reliable source in the slightest,
but my running theory is if she was born addicted to drugs, it explains her high weight and attention seeking from a young age.
Babies born addicted tend to be more needy and fuss constantly. Meth, if that's what it was, wrecks your pleasure centers too, and as a new baby you dont know how to self soothe, either. That's something you're taught after you have a few months of reassurance that your parents or whoever will come when you call to care for you.
If she was constantly crying, likely she was given lots of formula bottles to keep her quiet and asleep, and probably left in a swing or carrier when not fussing (by potentially neglectful parents who for all we know could have been indifferent about having kids, or weren't prepared/knowledgeable)
If thats the case, it would be easy for her to skyrocket in weight. As time goes on, when most babies begin to self soothe, her parents still only respond to the fussing because hey, that's what works and they're busy living the drug life.
It develops into a need for attention, and an understanding that throwing a fit or having a problem will get her food (which makes her pleasure centers happy) and also give her the attention she desperately craves.
It carries into adulthood because it was solidified by most if not all experiences she had as a kid. Increasingly neglectful parents, more drugs, foster homes, etc.
But knowing Albert it could all be exaggerated to shit.
