Oh I don't know, my brother-in-law and his girlfriend had a kid that they didn't plan for, basically she found out/realised she was pregnant at 8 months.
Anyway they were useless at bringing up their daughter, his idea of teaching her words was to point at things and continually repeat their name so she would say banana, banana, banana etc.
She has basically been taught life skills by her grandmother who dotes on her. If not for her I think she would still be in nappies and not able to string a coherent sentence together.
