Today Leó is 22 days old, and the nurse came over to do the weighing, measuring and genral check up.
So, here is the news:
Leó now weighs 6.3 kilo's and is 64 cm. tall :) (He was 5.3 and 60 when he was born)
So she (the nurse) says he is definitely drinking enough and there is no reason to check on him again until 6 weeks, when we have to go in and see a doctor.
Basically, things could not be better!
