My ds is 4 weeks today. We offer him 5oz feeds whenever he wants it which is usually every 3-4 hours. He will usually finish around 4oz of it. He was quite small at birth, 6lbs 14. The problem is he gulps it so quickly like we've never fed him before. I try and pace him with a dummy, burping etc but he screams desperately for it still so I assume it's hunger. He does suffer from gas quite badly and we do burp him a lot. I'm just worried we're over feeding him as it's easier to do with formula and it seems a lot for his weight but he's always desperate for it! We increased to 5oz as he was draining the 4oz bottles and I didn't want the air in the bottle on the last bit.
