Study: Nightime Breastfeeding = A Good Night Sleep?

A new study conducted at the University of Extremadura, in Badajoz, Spain found that moms who use a breast pump to express milk during the day and then bottle-feed it to their baby at night may be letting themselves in for a sleepless night.
The results also revealed that it was a bad idea for mom to express the milk at a certain time and then store it and feed it to the baby at a different time.
Research suggests that 5'AMP in breast milk might be fuelling the release of the sleep-promoting neurotransmitter GABA, while 5'GMP is involved in the secretion of melatonin,which helps regulate the natural body clock. 5'UMP is known to promote the amount of both REM and non-REM sleep.
The team has also been looking into whether the sleep-inducing nucleotides could be added to formula milk. In a separate study, a "night-time" milk was created by adding 5'AMP and 5'UMP to standard formula milk. Infants receiving this milk between 6 pm and 6 am, and normal milk during the day, fell asleep faster and spent longer sleeping than when they drank standard formula milk all the time.
