What do the Nurse's and Lady Capulet's comments about Juliet's age show about their relationship with Juliet in Romeo and Juliet?

The Nurse makes the effort to recall exactly how old
Juliet is through a series of unfortunate events. She recalls her own daughter which
likely gave her the ability to be a wet nurse for the Capulets, and the her husband used
to laugh at Juliet falling as a young walking girl. She recalls weaning Juliet off
breast-milk, and that produces a series of laughs.

Lady
Capulet simply recalls her age.

I think this demonstrates
that the Nurse has a fond relationship with Juliet. Nostalgic memories capture her mind
when thinking fondly over the years. For Lady Capulet, this is a matter of business. At
a certain age she feels she needs to tell her daughter to do specific tasks. This
accentuates the division between mother and daughter.
