Breastfeeding 🤱🏽

So I just had my baby girl on sunday 9/8/19 ❤️

So i breastfeed her she was latching on great and everything was fine but then the nurses told me to give her a bottle of formula because my milk supply hasn’t came in yet so i gave her that bottle that they gave me and she drank it just fine then i got discharged and sent home a couple hours later i fed her she breastfeed just fine then later when she was hungry again i tried to breastfeed and she wasn’t taking it she puts it in her mouth starts suckling and then she stops she starts to cry and won’t take my breast at all so i has to give her formula and she drank that just fine but now i don’t know if i’m feeding her enough i give her 1 1/2 oz (40ml) of formula she only drinks half of it sometimes a little more but i’m scared that i am not feeding her enough or if i’m over feeding her i am very emotional i think it’s because i’m sleep deprived along with being a first time mom and i’ve cried at least 6 times because i feel like i am not doing a good job 😩 my fiancé tells me not to worry that i’m doing great and i hope i am but i’m just so worried that i’m not doing anything right 😭 Do you guys have any tips on what i could do to get her to breastfeed again? or should i just stick to the formula?
