For the last 24 hours my baby has been refusing the bottle, not the actual milk, just the bottle. He'll drink the milk when I resorted to putting it on a spoon and feeding him that way but only when it was with rice. He's absolutely fine so there's nothing wrong, he just will not suck his bottle. I only a add a tiny bit of rice to the formula, so will he still get the calories from the milk that is added to the rice?? Thank you
