Ahhh, this is so common at this age lah, usually memang because direct feeding is easier and faster for them, especially if dia dah kena comfort susu straight from mummy! A few of my mum friends went through this, and honestly the trick is consistency, keep offering bottle regularly, maybe minta husband try at different times or even when baby is sleepy, sometimes they accept it better. Since you've already tried the faster teat, you could also try warming up the milk and the bottle itself, sometimes that helps bikin baby more willing to latch. But if this keeps happening or you're worried, best check with your pediatrician to make sure everything is okay.
