Thanks for posting your query,
The most likely thing that can happen if you stop breast feeding now is that:
1. You might likely develop a breast abscess
given the problem you are already having
2. Your daughter might continue suffering from neonatal colic
(given that she is already suffering from already) as artificial milk is known to be very associated with bowel disorder.
What do I suggest? Continue exclusively breast feeding her for up to 6 months and use analgesia such as paracetamol
or acetamenophen from time to time to manage the pain. The clogging might go off by itself as time goes. You can also increase the rate of breast feeding between 8-10 (or more) daily. Well I know that might be difficult if you are working. Trying giving your daughter breast milk directly from your breast most of the time. You may seek a gynobs opinion too.
Secondly, make sure your daughter is exclusively breast fed. If it comes to the worst, regarding her bowel problems see a pediatrician
