Wanting to focus on childhood psychology - BA Childhood and Youth Studies or BSc Psyc

I'm looking at the above courses and I just want to know what it's like, if you feel it's a good course that'll open doors? - I want to eventually work as an educational psychologist.

I'm wanting to focus on childhood psychology, but I'm not sure if it's better to pick BSc in Psychology as it's more focused on psychology, or would childhood and youth studies be something worth looking into, as it's more child focused?

Also, I work 5 days a week, but if I were to go down to 4 days, do you think I'd be able to study 120 credits a year? I'm impatient and I don't want to have to study for the next 6 years while working in a career that's not related to my degree, unless I were to volunteer elsewhere - which would take more time away from studying!
