breastfed baby won't take bottle😩

Christina
Babygirl having a hard time taking bottle I currently work only Sundays at spa doing massage next Weeknd I start both Saturday's and Sundays . Last Sunday she pretty much went on strike and had only drank 1ounce from 9am -230pm her dad and grandma were with her and she would not take the bottle . She's taken the bottle before in fact she did the past 5sundays In a row . We use tommee tippee bottles .. my mom says it takes a while for her to latch on but will eventually eat with her.. she even suggested I start givin bottle through out the week .. I want to go to work but I dont want her to not eat😩 
my best friends baby did the same thing today -1st day at daycare and went on strike from drinking the bottle 7am to 430🙁.. what do you ladies do? Seriously desperate 😔
