I have to correct myself. Last time i measured him was before 4 months(I just reviewed this thread). And he was 130 cm long(4,26 feet, 51 inch). and he weighed 1358 gramms (2,99 lbs). So he grew 5,75 cm (2,26 inch) a month. If this growth level continues, he will reach 2,53 meter (8,3 feet) when he is 3 years old.
