I am having this issue too. I have had several children finish their aspirations (one of the basic four) then so far even had one complete two full aspirations (social and physical/motor) and it still didn't count. I don't own many packs- just dogs and cats, first pet, horse ranch, and cottage living as well as the kits for backyard stuff and blooming rooms (not sure the exact name, I apologize). My sim is upset I am not completing her aspiration and gets sad, but the hard work to make sure her kids complete their childhood aspiration isn't counting. (photos provided of youngest daughter, Alysha, completing her aspiration while her mother, Arya, still has her's not completed). If you've been able to figure it out, I would be willing to have Arya adopt another baby or even have another child herself.
