Ebf wont take a bottle

Rebecca

My little one is 5.5m old and ebf. I’m trying to introduce the bottle (with my milk, im pumping) as I’m going back to work in July

So far she’s refusing it or just chewing on the teat. How can I encourage her to actually suck it?

Any milk that does end up in her mouth she just spits out

Anyone else had this struggle?
