Op you may need to read a little more widely on nurseries and child development.
Pretty much all studies show that for babies up to about age 2, being at home with a loving family member beats pretty much any childcare setting.
Nurseries can lead to better educational outcomes when compared with children from deprived homes - not all homes.
Bear in mind that in the uk, childcare work is poorly paid with a low educational requirement for staff. The focus is on care not education, and the reason is that care is more important than academic outcomes at such young ages. A great nursery nurse might be pretty terrible at maths but great at occupying and chatting to two year olds. This is why childminders are often just as good for babies and toddlers, and the same for being at home with mum/dad/nan. Each of these has the advantage of being a primary caregiver with whom the child bonds - which is essential.
Its great that you are hardworking but do not kid yourself. Doctors do not put their kids in nursery for 11 hours a day plus a weekend morning.
Most parents will try to have a work pattern that minimises childcare. Eg dad starts work 7am. Mum drops kids at nursery at 9 & starts at 9.30. Dad finishes at 4 & collects kids at 4.30, mum arrives home at 6.30pm. Both parents work full day but child only in nursery 7.5 hours. Plus in many families one parent condenses hours or drops to 4 days a week, so child may only do 7.5 or 8 hours a day, 4 days a week.
Or maybe dad works mon - fri 9- 6, mum works weds - sat, grandma has baby on Thursdays and they just use 2 days childcare.
I know no-one who used childcare 11 hours a day 5 days a week, let alone saturdays too.
