Irrational worry? Breastfeeding

Cara

So this may sound irrational but I am 9w1d and I know my breasts will not get as large as most of the women I know did though pregnancy. Even with the initial "growth spurt" I didn't even get a full extra size and I am a little freaked out about how breast feeding will work. I'm not tiny I wear C-Ds but I have always been slight so they are not as large as one would actually think. Anyone else worry about this? Every women I have ever seen breast feed has huge breasts and could easily feed with baby just laying on their lap without bending over them. I am probably crazy.
