Breastfeeding Issues-Help

mspano929

So I posted the other day that I was having issues with breastfeed.  My son has been really fussy for the past week.  I think he is teething but I'm not really sure.  In the morning he feeds no problem at all.  But in the afternoon/evening when my I put him to my breast he cries.  He will suckle and then pull off and cry.  I try to relax and help my milk let down but I cant see him cry.  I make a bottle and he takes it and is fine afterwards.  Sometimes I pump and sometimes I dont.  I dont know if I have a supply issue or what.  I dont know if he is weaning or knows its just easier to get a bottle.  I dont want to stop breastfeed.  I start to cry when I think about no being able to do it anymore.  I am on the verge of giving up but I can't.  Help me please!  TIA
