How educated are you on the biomechanics of breastfeeding? This is absolutely perfectly normal for a breastfed baby and like any other things there are disadvantages and advantages.

The advantage of bottle feeding formula is that formula has an incredibly high amount of iron which slows the digestive system, leading a child to feel fuller longer because things are moving more slowly which in turn delays hunger waking. The downside is that formula does not contain melatonin or induce serotonin production so doesn’t assist in making a child drowsy nor does it allow the parent to have the most restful night feeding experience possible.

The advantage of breastfeeding is that breastmilk does contain melatonin. If you sleep topless, your partner can latch the child while you stay essentially entirely asleep. The act of nursing induces serotonin (and oxytocin) production which allows the body to get rested on lesser sleep. I am a breastfeeding Mom and peer counselor and often joke that during the day, nursing is full service, but at night, nursing is self-service. I will be topless, but kid has to do all the rest. And they do. I doze during the nursing sesh. I nurse flat on the bed in the side-lying position so that if I do fall deeply asleep, my child is in the best possible circumstances vs falling deeply asleep in a chair or on a couch where kid will fall and be trapped between me and an arm or something.

There are, of course downsides to breastfeeding and the fact that breastmilk is digested more quickly than formula means there is a shorter time to hunger returns vs formula. (However, the quick digesting is super helpful when they have a tummy bug as you won’t have to worry about dehydration.)

The least advantageous feeding setup is to have Mom bottle feed breastmilk during the night. Mom misses out on those useful hormones which multiply rest benefits as those only come from nursing, the pumped day milk doesn’t have melatonin so won’t induce sleepiness in kiddo, but will still digest quickly.
