Breastfeeding worries

Zorayah • I'm a FTM engaged due Jan 8th,2016 with a little girl 💜❤️💗👶🏼
I'm 33weeks tommrow and I'm concerned I plan to exclusively breastfeed my daughter FTM and lately I'm really scared what if I can't or if my boobs are to small or don't produce enough milk any other moms worry or felt this way?? How's breastfeeding for y'all??
