...and the daytime/routine activities with the child was general care as...

My sister also babysit/take care of a baby´s neighbour (or also: of a neighbour child)

The baby´s name is Pollyanna. (since it´s a proper name, and the name is unique in number of ways. It singles out a person)

These are just suggestions to change your text, but I didn´t check it out for punctuation and other English grammar topics.
