Ryan is 16 weeks on Tuesday.. He generally has.. 3-4oz at 6am, same at 9 am and 12, 6oz about 3-4pm, 5-6oz at 5-6, same again at around 9 and 3-4am. Although he does seem to be having a lot at the moment - sometimes goes 1-2 hours before wanting another bottle. i.e. Today he had 5oz at half 6pm, and another 4oz at half 7pm! x
