This is when a baby swaps his/her days for the nights and starts to nurse more
at night than during the day. Reverse cycling is normal and does not
necessarily need to be changed unless the mother feels that she can’t cope. It
doesn’t matter when your baby is receiving milk, just as long as he/she is
getting in enough. Don't know whether your baby is drinking enough?
A baby might want to breastfeed more at night because he/she has the need to be close to his/her mother and “reconnect"; since he/she hardly sees the mother during the
Reverse cycling for a working mother is often used and encouraged, as
a way for the mother to continue breastfeeding. This means less pumping and bottles during the day.
Baby Only Breastfeeds in the Evening
by Raphael (Dormaa Ahenkro, Ghana)
"A mothers job demands that her baby only suckles in the evening when she returns from work, can that cause stomach ache and running stomach in the baby?"
Re: Baby Only breastfeeds in the Evening
"Yes, especially if mom has an overproduction of milk. What happens is that the mom's breasts are overfull - the baby drinks but only receives the foremilk (because there is so much of it)
Foremilk is the watery milk in the front of the breast's milk-producing cells (alveoli), this milk is high in lactose which causes the runny tummy and colic symptoms.
Has she just started working again? It could be because her body has not yet regulated the amount of milk needed for the baby. Her milk supply should drop within a couple of days, which means that baby will stop having runny stools and tummy ache. It will take a while, and her body will start producing just the right amount of milk needed for the night feedings.
If the oversupply continues (which is very rare, if mom is only breastfeeding once or twice per day) she can use certain herbs to decrease supply.
