He has 5oz bottle made up every 2 hours and most of the time it takes over half an hour to get it down him as he always seems hungry and I've tried leaving it longer between feeds so he'll take more but it still takes him about half an hour plus to have it. At about 8 weeks he was going 4 hours between feeds at night and over the last few nights is waking every 2 hours or so and then having about 3-4oz. During the day he'll have a few half hour naps and if we go out he'll sleep up to 3-4 by then I'll wake him if its after 4.30pm. Unlike his older brother at that age he'll not have a dummy to comfort suck on. Using Avent size 2. Bedtime 8-9pm then he'll wake 5-8am. Thanks
