baby doesn't want to eat Solids

So, baby girl will be 8 months on Monday. She seems very interested in food and watches us eat all the time, but, when I try to feed her she doesn't really eat much. I have been trying to feed her solids for about 3 months. So far her favorite thing is pureed apples although she does eat oatmeal with banana almost every morning. Other then that she just wants to nurse.... All the time... it's exhausting. She won't take a bottle so I can't have anyone help feed her. Anyone else have this issue with their baby? My 1st born started solids at 4 months and never had any issues eating. She nurses at night a lot, mostly because I think the breastmilk does not fill her up. Anyone else going or went through this? Any advice?
