Tobily - I just compared those charts on the WHO site with what's in my blue book - and the WHO's weights are higher than the blue books! Shouldn't they be lower?

eg.. Girls at 6 months

Blue Book (CDC)
50th percentile is 7.2kg
97th percentile is 8.8kg

WHO charts
50th percentile is 7.6kg
97th percentile is 9.4kg

pfft - just goes to show not to go by ANY charts! LOL.

ETA: ok... am having an obviously boring night to be doing this.. but anyhoo LOL...

Found this on the CDC website
Are these charts appropriate for exclusively breast-fed babies?

The 2000 CDC growth charts can be used to assess the growth of exclusively breast-fed infants, however when interpreting the growth pattern one must take into account that mode of infant feeding can influence infant growth. In general, exclusively breast-fed infants tend to gain weight more rapidly in the first 2 to 3 months. From 6 to 12 months breast-fed infants tend to weigh less than formula-fed infants.
So I then looked at the charts again at 12 months this time

Blue Book (CDC)
50th percentile is 9.5kg
97th percentile is 11.8kg

WHO charts
50th percentile is 9kg
97th percentile is 11.4kg

So yep - seems the WHO charts do reflect it better Interesting tho.. I didn't know that breastfed babies put on more weight in the early months. So I've learnt something new today! But surely knowing this would put more pressure on mums struggling with breastfeeding? coz these charts have higher weights in those early months.

*sigh* I reckon scrap the charts.. and just be sure there's some kind of weight gain and a happy, weeing, pooing baby LOL.

Ok.. think I'll go to bed now. LOL.
