Breastfed 🤱🏽 baby doesn’t want to bottle feed

Soooooo my 3 mo baby (5th child) doesn’t want to take the bottle. He’s only had one bottle (formula around 1 mo). I’ve tried twice recently to give him a bottle of formula, once similac powder formula which was what he drank the first time and today I tried enfamil premium newborn ready to use formula (liquid) and he’s just not having it. He won’t even suck the nipple and the milk that drips into his mouth he spits it out, but as soon as I start to go for the snaps on my breastfeeding bra he gets right into position 🤦🏽‍♀️. I breast fed all of my children, the first only 10 days (I was 17) and the other three pregnancies (27, 29, & 34) I breastfed in the range of 2-6 months (each pregnancy I got better at it and more mature, so I breastfed longer) supplementing with formula each time never having any problems with the transition from breast to bottle. I need help figuring this out. I’m in a wedding at the end of the month and mommy needs a life too! I own my own business and thank God because I have to take him to work with me... I have a medela breast pump but I find it hard trying to find time to pump between feeding him work and everything thing else that me and the other kids have going on. I also worry that if I pump it he still may not want the bottle and my milk is wasted 😫 what should I do 🤷🏽‍♀️? Help please, I mean I still want to breastfeed 🤱🏽 him but I also need to be able to leave him with his nana... does breast milk have flavor??? I think he wants to eat what I’m eating 🤦🏽‍♀️

He’s right where he wants to be 😍
