Have a look at this link.
I did a reflective account on 3 children of different ethnic groups (jordanian/scottish parents, jamacian/welsh parents and greek/french parents, taking into account the parents requirements/preferences on how to care for their child's personal hygiene.
Some parents require specific creams after nappy change - certain oils on hair - specific combs/brushes etc
Also just a note - I would not refer to children as black in your work, actually confirm what their ethnic background is when writing up your unit.

Hope this helps
