One common concern among breastfeeding mothers is whether their baby is getting enough milk. When a baby nurses directly, there is no measuring cup to show how many milliliters they have taken. This can make every cry, short feed, or request to nurse again feel like a reason to worry.

Dr. Maria Carmela “Macy” Declerck, a general pediatrician, diplomate of the Philippine Pediatric Society, member of the Philippine Society of Breastfeeding and Lactation Medicine, and International Board Certified Lactation Consultant, says no single sign can answer this question. Feeding frequency, swallowing, diaper output, weight, and the baby’s behavior all need to be considered.

Colostrum is the thick, yellowish milk produced during the first days after birth. It contains antibodies, immunoglobulins, and other factors that help protect the newborn. The amount may appear small, but a newborn’s stomach is only about the size of a small calamansi on the first day. A baby may take about six to 12 mL at each feeding during the first 24 hours.

“Moms should not feel the pressure to produce several ounces of milk immediately upon delivery. This takes time over the course of the next few days,” she tells Manila Bulletin Lifestyle. Milk production increases as colostrum is removed from the breast and the baby continues to feed.

Wet and soiled diapers are among the clearest signs that a baby is taking in milk. Output is low on the first day and should increase as the baby feeds more frequently and the mother’s milk supply grows.

A newborn may have only one or two wet diapers and at least one bowel movement during the first 24 hours. By the fourth or fifth day, parents can expect around four to six wet diapers daily. Once milk production is established, more than six wet diapers in a day is not unusual.

During the early weeks, three to four bowel movements a day can also be reassuring. Since stool frequency changes as babies grow, consider diaper output together with weight gain, feeding behavior, and activity.

Some weight loss after birth is expected. Newborns begin passing urine and meconium, the dark, sticky stool produced during the first days of life. Dr. Macy says many newborns lose around seven to 10 percent of their birth weight, beginning on the second or third day. The loss usually peaks by the fourth or fifth day, when the mother’s milk is also beginning to increase.

A baby who feeds adequately should begin gaining weight and generally regain their birth weight by the second week. Weight loss of more than 10 percent, particularly if it reaches 12 percent, should be assessed by a pediatrician or lactation consultant.

A good feeding session should be comfortable for both mother and baby. The baby’s mouth should open wide, with the lips turned outward and the nipple and part of the areola inside the mouth. “A comfortable and successful latch feels like a gentle, tugging feeling at the nipple, not a sore or burning sensation over it,” she says.

Movement along the jaw and the sound of swallowing may indicate that the baby is taking in milk. Clicking or smacking sounds and continued pain may point to a shallow latch. If feeding hurts, gently release the latch and try again. Seek professional help if the pain continues.

Most newborns breastfeed every two to three hours, although some may nurse every hour. In general, they feed eight to 12 times within 24 hours. Dr. Macy recommends feeding a healthy, full-term newborn when the baby asks instead of following a strict schedule.

Breast milk is easily digested, and a newborn’s stomach remains small, so the baby may become hungry again soon after feeding. Babies may also nurse repeatedly over several hours. Called cluster feeding, this can help increase milk production and often happens during a growth spurt. It does not automatically mean the milk supply is inadequate.

Crying, short feeds, or low pumping output do not prove an inadequate milk supply on their own. The amount collected may be lower if the baby has recently nursed. Pumping frequency, timing, and pump settings can also affect output. A baby who relaxes after feeding can be reassuring, but regular swallowing, diaper output, weight gain, and alertness are more dependable measures.

While eight to 12 feeds a day is usual for newborns, feeding fewer than six to seven times or having fewer than three to four wet diapers within 24 hours after the first few days may indicate dehydration.

Dark or concentrated urine, increasing jaundice, excessive weight loss, repeated vomiting or regurgitation, fast breathing, poor feeding, reduced activity, and unusual sleepiness also require prompt attention. Premature babies and those with oral or jaw concerns may need additional feeding support. Tongue or lip restrictions can sometimes affect latching and milk transfer, but each case must be assessed individually.

A mother shouldn’t wait for breastfeeding to become painful or exhausting before consulting a lactation professional. Support can begin during pregnancy, especially when there are concerns about breast anatomy, previous surgery, medical conditions, or an earlier difficult breastfeeding experience.

During an assessment, the lactation consultant reviews the mother’s health and pregnancy history, the baby’s birth and feeding history, positioning, latch, swallowing, milk transfer, and weight.

At home, families can keep track of feeding frequency and diaper output, then bring these notes to the baby’s checkup. A visit to the pediatrician a few days after leaving the hospital can also help confirm that feeding and weight gain are progressing well.

Breastfeeding takes practice for both mother and baby. There is no need to wait until feeding becomes painful or exhausting before asking for help.
