Bottle feeding

I am trying to give my ebf baby a bottle, how do I know if he doesn’t like the milk or the bottle??

Persevere for a few days, same bottle same milk, same teat. If not working change one of these 3 things at a time x

If they don’t like it they just don’t drink it my baby will absolutely not take formula but is fine drinking my milk from the bottle

I use a cup with my little girl. She wouldn't take a bottle but will take a cup of pumped milk
