So I mentioned that I had noticed some changes going on with her body and she says to me:
"I've noticed that too mom!" and then she asked me what they were for.
I explained that when she got older and married and had a baby that she would feed the baby with them.
"So I'll be like a cow!"
It actually went very well, it wasn't awkward and she was very receptive. So we have the changes in our bodies and monthly issues done with.
Phew- 1 down (well partly- I didn't go into how the babies get in there yet) 1 to go!
