OrganicDinosaur explaination via NF and her translation of the line:
^ Going to be the best translation unless TakL shows up to throw his words in.
OD has a thread on NF to ask her about any mistranslations on reddit right now.
「…私は…パパと…ものごころついた時から会ったことがない…」
" ...Papa and I.....We've never/haven't met since as far back as I can really remember."
The 物心/ものごころ means like 'ever since I've been aware of things' or like 'since I've been able to understand the things around me'.
= So the meaning is like she personally has no recollection of Papasuke while she was growing up.
