Yes, yes, yes, I agree with all the above.
Just spending a few hours with my sixteen month old grandson, I find exhausting.
I used to have him for a ten hour day when DD was working.
He wasn't so active then, but now walking, it's a nightmare. Very stressful.
I felt quite ill after they left.
I think if you agree to do this, you will probably be ill with stress and exhaustion.
Its horrible having to think like this and you feel as if you are going into battle every time you have a conversation about don't you?
Look after your health, it's important.
