It's called reverse cycling.
This is a term that is used to describe the nursing pattern of a baby who nurses a lot in evening and (or) night time hours rather than the "normal" daytime hours. And it has everything to do with her missing me while I'm at work. When I think about it, I nurse a lot after I fall asleep. She and I wake up frequently to nurse. And she only gets one bottle a day while I'm at work. She likes to hold out for the real thing. Who wouldn't?
Here's a clip of what I read:
"A working mom can be confused by a baby who is reverse cycling because she is providing the baby nourishment while she is away at work by leaving pumped milk or formula, yet baby still wakes often at night to nurse. It is very important for moms to realize that nursing a baby is not 'just' about food. Babies who are away from mom for any period of time often have a great need or desire to 'reconnect' with her, and thus baby 'reverse-cycles', but it may not be 'all about' nutritional needs.
Other times baby will simply take enough expressed breastmilk to hold them over until they are reunited with mom. Moms may worry about the meager amount of milk baby takes in during the day, however, if the baby has unrestricted access to the breast at night and nurses often, then baby almost always takes in enough milk for optimal growth and development. Allowing baby to reverse cycle often helps mom maintain milk supply when she is working, especially if she has limited time to pump milk during her workday.
A working mom may find that if baby reverse cycles, she may not need to pump as much breastmilk for baby to have at the sitter. Baby sort of goes into low gear, sometimes sleeping more while at the sitter's and then when reunited with mother, baby will nurse frequently to sate the nutritional and emotional needs.
Most breastfeeding experts agree that the easiest way to cope with a baby who is reverse cycling is to co-sleep, or sleep near the baby for 'easy access' throughout the night."
Okay. I feel better now. Maybe she's not really weaning. Maybe I just don't realize how often I nurse at night. It's at least three or four times a night after I already fall asleep; we've co-slept since the day she was born. What can I say? She loves me.
