So, before anyone rushes in, no he is not starving, but he will not stop part way through a bottle to be winded. Since he was born, if you try to stop a bottle to wind him, he will scream and cry until you give him the bottle back, but he is getting worse with it.
I always get him his food and a bottle ready before he starts (well within the 4 hours since his last meal), so he never actually asks for food but if he sees his bottle he will scream and cry real tears for it, so I have to hide it whilst I'm trying to wean him. He is definitely not starving, having just had a large bowl of porridge for breakfast and veggies and a pudding for other meals, he just REALLY wants that bottle. He also sleeps from about 9pm through till 7 or 8am and he wouldn't do that if he hadn't had enough to eat through the day.
Any ideas as its heartbreaking to hear him so upset over it.
