I have an appointment at 1:45 for an ultrasound, but my husband will be at work and my daughter has to stay with my husband's step sister and her kid(her daughter is not nice and a very big brat, the mom also doesn't do much of anything) I'm sad cuz I'll be alone to do this and because I love my husband and most his family but am very nervous about leaving my daughter with them especially since it will be around nap time.

I feel like I'm in such a predicament....I almost called in to reschedule so I wouldn't have to take her all the way to Lemoore when I live I live in Hanford and my appointment is here as well.
