Do Older Babies Need Night Feedings?
Has somebody told you that your baby doesnâ€™t need to breastfeed at night past a certain age? This age often varies by advisor. However, science tells us that in many cases, this simply isnâ€™t true.
Why? Babies and mothers are different and these differences affect babyâ€™s need for night feedings. Some babies really do need to breastfeed at night, at six months, eight months, and beyond. This is in part because if their mother has a small â€śbreast storage capacityâ€ť and tries to sleep train her baby, her milk production will slow, along with her babyâ€™s growth. To find out what this means and if this applies to you, you need to know the basics of how milk production works.
Degree of Breast Fullness
Two basic dynamics are major influencers of milk production. The first, â€śdegree of breast fullness,â€ť refers to a simple concept: Drained breasts make milk faster and full breasts make milk slower. Whenever your breasts contain enough milk to feel full, your milk production slows.1 The fuller your breasts become, the stronger the signal your body receives to slow milk production.
Breast Storage Capacity
This second basic dynamic refers to a physical characteristic known as breast storage capacity, which varies among mothers.2 This physical difference explains why feeding patterns can vary so much among mothers and why one breastfed baby does not need to breastfeed at night while another one does.
Breast storage capacity is the amount of milk your breasts contain in your milk-making glands at their fullest point of the day. Storage capacity is not related to breast size, which varies mainly by how much fatty tissue is in your breasts. In other words, smaller-breasted mothers can have a large storage capacity and larger-breasted mothers can have a small capacity.
Both large-capacity and small-capacity mothers produce plenty of milk for their babies. But their babies feed differently to get the daily volume of milk they need.3 After babyâ€™s first month, a mother with a large storage capacity may notice that her baby:
- Is satisfied with one breast at most or all feedings.
- Is finished breastfeeding much sooner than other babies (sometimes just five minutes).
- Gains weight well on fewer feedings per day than the average eight or so.
- Sleeps for longer-than-average stretches at night.
If this describes your breastfeeding experience, your baby may already be sleeping for longer stretches at night than other babies you know. But if after the first month of life your baby often takes both breasts at feedings, feeds on average longer than about 15 to 20 minutes total, typically takes eight or more feedings per day, and wakes at least twice a night to breastfeed, your breast storage capacity is likely to be small or average.
Again, whatâ€™s important to a babyâ€™s healthy growth is not how much milk he receives at each feeding, but rather how much milk he consumes in a 24-hour day. Breastfed babies of both large- and small-capacity mothers receive plenty of milk, but their breastfeeding patterns will necessarily differ to gain weight and thrive.4 For example, a baby whose motherâ€™s breasts hold six ounces or more (180 mL) may grow well with as few as five feedings per day. But to get this same 30 ounces (900 mL) of milk, if a motherâ€™s breasts hold only three ounces (90 mL), a baby with a small-capacity mother will need to feed ten times each day. (This may not apply in the same way to a mother whoâ€™s pumping.)
How These Dynamics Affect Night Feedings
How does this apply to night feedings? A mother with a large storage capacity has the room in her milk-making glands to comfortably store more milk at night before it exerts the amount of internal pressure needed to slow her milk production. On the other hand, if the baby of the small-capacity mother sleeps for too long at night, her breasts become so full that her milk production slows.
In other words, if you are a mother with an average or small breast storage capacity, night feedings may need to continue for many months in order for your milk production to stay stable and for your baby to thrive. Also, because your baby has access to less milk at each feeding, night feedings may be crucial for him to get enough milk overall. Again, whatâ€™s important is not how much milk a baby receives at each individual feeding, but how much milk he consumes in a 24-hour day. If a mother with a small storage capacity uses sleep training strategies to force her baby to go for longer stretches between feedings, this may slow her milk production and compromise her babyâ€™s weight gain.
Each mother-baby pair is unique. Babies will outgrow the need for night nursings at different ages, so a simple rule of thumb doesnâ€™t consider either the emotional needs of the baby or his physical need for milk.
