My 5mo is starting to get to that 'easily distracted' stage while feeding but instead of unlatching she's just clamping down then moving her head away. Last week she did it so often on a day of intense feeding that she mangled my nipple and caused a big crack to appear. Lasinoh has healed it but she's done it again a lot today. Is there any way to discourage it? It's absolute agony when she does it and she does it so quickly there's no way to anticipate it and unlatch her.
