Hugs hun, Im sorry for so many negative responses - this is a REALLY controversial topic and I know that wasnt your intention. I've been on BH for 5+ years (different username originally), and I dont think I've ever seen a SOS thread that wasnt hotly debated - so dont take it personally, its not just you!
Just to add more confusion, I'll tell you my story of how i stumbled upon SOS. My first baby I thought I will just demand feed, baby will feed when hungry, sleep when tired, simple, right? Well it turns out some babies don't 'get' to demand feed. I had a very lazy feeder/ what has been called a 'super sleeper'. When I let her demand her feeds & sleep when she wanted, she just slept and slept for hours. Thankfully I was still in hospy at the time, but she went 10+ hours in between feeds, I could not wake her to feed her, midwives seemed very blase 'oh she'll demand when she wants it', and it was only when a dr came to check on us & checked her blood sugar that i was told her blood sugar was very low, she was very weak and sleepy, and was not able to demand any food. She lost 13% of her birthweight and took over a month to get back to her birthweight. The advice feom LC's, dr's, etc? Wake her every 3 hours & make sure she doesnt fall asleep at the breast before getting a full, proper feed into her. So the whole 'go with the flow, baby will demand when she is hungry' thing got thrown out the window. Thats why SOS fit so well into what I was already doing. I always put bubbas needs first, when she became strong enough that she did start to demand, I NEVER refused a feed because the routine said it wasnt time. I used it flexibly, but it did help. Some babies dont follow the rule of 'put them to the boob at every cry and they will feed'. Some, like mine, would just fall asleep whilst wasting away.
