baby keeps waking to nurse

Carly

my daughter is 1 and continues to wake at night to nurse..sometimes just once, other nights shes up a few times. Although i love nursing and want to give her all of my attention at night since I work during the day, i really want to break this habit...especially knowing that she doesnt need the calories and I also just found out im pregnant! so i need to get my sleep at night. I just have mom guilt about being away all day... any advice?
