Yes she is, but i like to go outside once in a while to check her better, however i dont want to disturb her, but i dont want to "not be there: if something goes wrong.
I have the binoculars almost permantly attached to me now!
As long as you can see her from the house, just let her be unless you see something wrong. This is good advice - my husband gives it to me everytime I have a mare ready to foal. I don't listen but it is good advice :)
