Wow. I work two days a week, so three days a week I spend around 10 hours alone with both kids. I have no visitors and hardly any friends yet outside of work. I am getting involved in a stay at home moms group but they are all super talented at knitting and sewing and that's what they talk about.
I just joined the YMCA. They have swimming lessons for babies and kids and also yoga for mom's with babies. Are you involved in anything like that?? That may help a little. I know it has done wonders for my mood.
Fourteen hours a day would be so very hard. You hang in there. Your daughter is so beautiful.
