Zoe definitely isn’t alone in her lopsidedness – her photo has over 4000 likes and almost 200 mums commented that they too have experienced lopsided boobs while breastfeeding.
Whether they are breastfeeding or not, most women have slight variations in breast size, just as most of us have slight variations in shoe size, for instance, and when it comes to producing milk, it’s common to have one breast that is a better milk maker than the other. It’s no fun though, when one breast becomes much bigger than the other and your baby favours the ‘good’ side, perpetuating the extreme lopsided look.
Why does one boob make more milk?
The basic rule of milk production is that the more milk is removed, the more milk your breasts will produce, so uneven breast size can be influenced by your baby feeding more from one side than the other. A preference for one side can be either baby driven or mother directed. You may find it more comfortable to feed on one side so feed your baby more often on that side or your baby may have a preference so feeds more from one side. And when baby feeds more from one side, this breast will make more milk – and become bigger!
Reasons your baby prefers one side.
Faster milk flow – one breast may have more working milk ducts and alveoli so produces a greater volume of milk or if you have had breast surgery on one side this also can affect supply in that breast . One breast can have a faster milk flow or more forceful milk ejection reflex and whether your baby prefers a faster flow or is overwhelmed by this, could determine which side is easier to feed from.
If a slow let down seems to be an issue, you can start your baby on the preferred side then when you get a letdown and your milk flows faster, switch sides. You can also try breast compressions to encourage a faster flow to to keep your baby feeding on that side.
Nipple shape – Just as most women have breasts that are asymmetrical, you are also likely to have slightly (or more pronounced) variations between nipple shape and size, making one side easier for your baby to latch. This too can influence breast preference and feeding behavior.
