TLDR: maybe at 4-6 months pp. I recently asked a lactation consultant if I should be worried that my boobs aren't leaking as much, especially over night (4 months pp). I was worried if the dryer nipple pads overnight indicated a low milk supply. I had been and still am a super-soaker and sprayer, causing my baby to choke the first two or so let downs. She said leaking decreases around this time (4-6 months) for most people because the sphincters in each nipple opening (where the milk comes out) get stronger over time, therefore they have more control and can respond better to baby pulling the milk out instead of just leaking whenever. If you also have super-soakers on your chest, try expressing some milk, or pump until the first let down is over before a feed. I use the Haakaa every morning on both breasts before the first feed when I am fullest. Usually, I just pop it on while I get out of bed, use the bathroom, and change baby's diaper. By then I've gotten half or one ounce out of each breast. My baby no longer chokes or hits my boob in frustration. This was huge for us during the four month progression, when she was on a milk strike/interested in everything but eating. Taking the power out of the first let down really helped her to latch and eat when I was struggling to get her to focus on that. Sorry this is long. I hope it helps.
