Oversupply refers to when a mother produces more milk than what her baby
needs, it is also commonly called “hyperlactation". An oversupply of
milk can often lead to lactose overload / overabundance of foremilk
(watery milk at the beginning of a feed).
Fore-milk contains much less fat than what hind-milk contains (the milk that comes closer to the end of a feed). Fore-milk is also high in lactose, which can cause difficulty of digestion. This is due to the fact that her baby may not have enough Lactase available to break down the Lactose in the small intestine.
Symptoms of lactose overload / Foremilk imbalance
You may experience one or more of the following:
Baby may pick up weight slower, normally or more than expected. Some babies may gain too much weight, about 1kg every month.
Colic symptoms including inconsolable crying for more than 3 hours every day, for more than three days, every week and for more than three weeks.
Watery, green, foamy and explosive stools.
Fussiness while breastfeeding, more towards the end of a feeding session.
Flatulence (gassiness) and signs of abdominal pain.
Symptoms of oversupply
(Not all mothers with oversupply issues have babies that struggle with foremilk imbalance)
Pain within the breast with a let-down (when the milk starts flowing).
Correcting and dealing with oversupply
To correct oversupply a mother needs to get her baby to drink more of the fatty hind-milk. She can do this by allowing her baby to alternate breasts by feeding from only one breast for a 2 to 4 hour period (depending on how severe the oversupply issue is) The other breast should be pumped just a little for comfort, so that it does not become engorged. Some Moms have such bad oversupply issues, that they may only need to switch breasts every 6 hours. A mother should first start off with a two hour gap and then increase this, if the issues persist.
Breastfeeding a baby in a reclined, semi upright position can help if the baby struggles with the flow of the milk.
Let your baby breastfeed on demand and let Baby decide when he/she has had enough. Do not keep your baby on a strict feeding schedule.
