I was told that when they have an overfull tummy they act like they want more ie rooting and snuffling and chewing on fingers. My LC also told me that the sucking relfex also gets the gut moving which is why they can tend to suck more when they are overfull. Instead of feeding her again when you think she's had enough, try a dummy. Two of mine needed a dummy and one self settled with thumb. Only one out of 4 settled on his own.

Do the poos look like satay sauce? If they do then that's pretty normal Have you seen much baby poo? Are you comparing what you are seeing to that of a formula fed bub because they are very different!

ETA sorry I replied then noticed there was a second page! Glad to see you are doing better
