having to supplement...I'm so sad

Isabel • Anything can happen

so mybaby is 3 months old and I've been having to give her the bottle 1 to 2 times a day..we breastfeed at night but during the day she sucks on her hand alot (which makes me think shes not getting enough) or gets fussy on my breast. I also notice she falls asleep too quick on my breast. I thought she had a good latch, the only time I know for sure she is extracting my milk is when I'm engorged and she

finishes both breaths and then starts sucking on her hand AGAIN! LOL .I never offer bottle after that I just usually stick her back on and she sucks...idk I feel confused because I dont want to have to give her formula!! Also as far as the sucking, I know babies have that sucking reflex but she refuses pacifiers....idk if this is wrong someone said to not let her use me as a pacifier but everyday at bedtime she falls asleep on my breast..and I believe she does indeed use me as a pacifier lol I'm sure she gets milk then too? idk I'm so confusing and this is my 3rd child but I've never breastfed this far . any advice. on what to do or just tips would be extremely helpful thNx
