1) The frequency day
Most babies have the occasional day or two when they feed frequently and take in a lot of milk, leaving the breasts feeling soft. These have been described as frequency days and are an example of a normal breastfeeding pattern. Other than feeding more often, their behaviour does not change significantly on such days.
2) After the frequency day
The frequent feeding will increase the milk supply. After the frequency day is done, babies may feed less often for a day or two as there is more milk available in the breast. In addition, the babies might still be a little full after taking in a lot of milk on the frequency day. This may leave mothers feeling full.
There is no ideal name for these days; we will just call them infrequent days.
3) Return to the usual pattern
After the infrequent day(s), babies will return to their usual breastfeeding patterns.
4) When it is not a frequency day
If babies continue to suddenly feed more often for more than two days, it is unlikely to be a frequency day. Rather there might be a change in the baby’s health or a decrease in the amount of milk available to the baby. In this situation, the baby is also likely to be less happy than normal.
