My boys paediatricians all recommended monthly weigh-ins as it's a bit more accurate than weekly (because they can fluctuate so much). Brendan follows his own curve, has never been 'by the book' and Tristan's chart looks like steps. One month he might only gain 40grams or so but the next he would gain 500gm. It varied so much. Tristan's paed and CHN always looked at the bigger picture, his weight was only a small proportion of their concern.... they looked at development, over-all growth and how happy he was. At 17 months he is *just* on the 3rd %ile.
They were happy with an average of 100 gram weight gain over a week.
