Re: Pushes away/cries
Since you use bottles regularly I'm going to guess that it's probably because he has to work a bit harder to get milk from your breast than he does to get it from a bottle. Since it drips from the bottle with no effort on baby's part and they have to actually suckle to get milk flowing from your breast.
Have you noticed whether you have a particularly strong letdown? It could also be once the letdown happens it's taking him by surprise and spraying more forcefully than he's used to from the bottle.
Normally I'd say try to move away from the bottles to eliminate the confusion, but it sounds like in your case it is necessary at the moment. And ultimately I wouldn't say it's a problem unless he starts refusing the breast altogether. It sounds like once he gets past his initial frustration he does fine. But something you could do that might help is to try expressing a bit of milk so that it is on your nipple and flowing a little before you latch him on- so he can taste it and knows it's there. If you think you might have a forceful letdown you could nurse him leaning back or even let that first letdown spray into a washcloth (or catch it in a bottle since you are supplementing).
