My DS is 13 months. He nurses about 5-8 times per day. He is very distracted during the day and he can drain one side in about 2 minutes, if he stays on that long. My letdown takes anywhere from about 30 sec to one minute to occur after he starts sucking. A lot of times he will suck for a few seconds and then pop off, right before letdown or right after it starts. I cannot stand this! I hate the feeling that the milk is about to start gushing and then it has nowhere to go. And once he pops off, there is no way to make him go back on. Does this happen to anyone else, and how do you deal with it?
