Feeb - I think DD was the closest to your DS' weight at birth - she was 3950gms when born - and at 8 weeks - is 4.98 - so has gained a kilo in 7 weeks. Not sure if that makes you feel better? She is formula fed, so should be on different charts than BF ones anyway...

And you shouldn't be comparing babies anyway!!! As long as he IS gaining, and plenty of wet and poopy nappies - you should be giving yourself a pat on the back - not beating yourself up.
