Okay, just been through all the cards, and made some notes. This is not all of them - these are just the babies I've had since July, and I've noted the number of times they've fed since July 25th alongside their weight.
From July 25th to today is 32 weeks - 224 days. I feed every five days, and a couple of times have pushed feeding back a couple of days, so the actual number of feeds offered has been 43. Here is a comparison of their weight and the number of feeds they actually ate. The right column orders them in order of number of feedings taken, the left column in order of weight.
72g - 42 | 43 - 58g
58g - 43 | 42 - 72g
48g - 41 | 42 - 26g
38g - 42 | 42 - 38g
38g - 41 | 41 - 48g
34g - 29 | 41 - 38g
28g - 34 | 37 - 20g
28g - 32 | 35 - 22g
26g - 42 | 34 - 22g
24g - 34 | 34 - 28g
22g - 34 | 34 - 24g
22g - 35 | 33 - 18g
20g - 37 | 32 - 28g
18g - 33 | 29 - 34g
18g - 26 | 26 - 18g
16g - 22 | 22 - 16g
Make of that what you will!
