Good grief CatDean. I'm sorry, but I'm going to have to urge you to listen to an random stranger on an internet forum rather than your doctors. I am and by that utter utter rubbish and potentially damaging advice.
Please phone one of the helplines of the true experts to verify what I am saying though.
You lo can sometimes go as long as 3 hours between feeds but please don't force the issue. Whilst building supply, try to feed every 2 hours during the day.
Your baby is quite possibly hungry and is fussing at the breast because your breasts are not satisfying him, not because they can't but because you have been badly advised to interfere in the relationship between baby and boob and the supply and demand.
If this wasn't enough, the bottle is replacing a breastfeed at the optimum time for driving supply.
From everything you have said so far, thankfully there appears to be no reason why you can't get back on track fairly easily.
Forget the bottle for now, and have a nice weekend babymoon. You and baby pamper weekend should see you alright. No restrictions on feeding, no restrictions on cuddling or falling asleep in your arms/on the breast. Offer both breast with each feed, and then offer no.1 again and continue until there really is no more interest.
Try to relax yourself before every feed because stress can inhibit let down which might frustrate the baby.
The shape of your breasts has nothing to do with your ability to feed, only perhaps the positions that you find most comfortable.
Now I'm not saying your baby doesn't have thrush or reflex, but given your very poor advice I'd say it was that that is more likely to be the problem.
Again, I'd advise you call one or more of the helplines to verify what I am saying.
Please don't give up because of this seemingly easy to fix issue.
Good luck.
