Second time mom/ breastfeeding

Alisha
So with my first pregnancy my boobs got huge! They were hard/full and just really big and they grew very fast..all the time! I was always buying new sports bras. They were so big it was like I got a boob job! I was able to breastfeed like I wanted but now I'm in my second pregnancy, being 34 weeks and 5 days it's almost over and my boobs just feel normal like how they were before I ever had kids, they did get a little bigger but the fullness isn't there all, not hard just regular boobs really lol. And with my 1st kid around this time I was wearing a 38D! Now I'm wearing a 36c.. Will I be able to breastfeed again or are "the girls" out of order ? Anyone else been in this situation ..? Is there anything I can take to help with milk production ..because I'm worried I won't be able to breastfeed. Idk if this is normal after having your 1st kid ( the whole boobs not comparing to how they were the first time around)..? can that determine whether I'll be able to breastfeed again, the fact that the girls aren't the same as they were when I was able to breastfeed with my 1st? Omg help:/
