I have a friend who quit BF because she thought it was her milk and with my first i quit thinking i didn't have enough milk and that's why he cried so much.
both of our babies had reflux so eating did hurt regardless and the formula was actually harder for them to digest
what exactly is your little one doing ?
anyway i did relactate, but it takes so much more work to relactate, and much more involved, getting LO used to the breast again which she may never take again, it took me 3 months almost to get my little one back to the breast when we only quit for 6 weeks. i personally wouldn't wean. but that's because i wish i never quit and had to relactate in the first place. it would of been much easier on me just to nurse.
