I was in hospital for 4 days after he was born, so unless you count the day we bought him home in the car (day 5), we took him out in the pram on day 6 for an hour long walk around the village where we live. I was told to take him out as much as possible, but not in direct sunshine as he had jaundice and it cleared up really quickly after we did this. I´ve tried to get out at least once a day ever since.
