My 3 month old won't stay latched on correctly. he will latch then pull back, narrow his latch, stretch my nipple and pull off before I can release suction. I know that he knows how to stay on correctly. Do they have bad habits at this age, and behavioral issues at the breast. I am not sure what else it could be. My nipple is sore, and I have become so frustrated with this that it is not enjoyable to feed him at all. Just frustrating and irritating. Any suggestions, I am not sure what to do to help things.
