Like everyone else said go for it!!! It's often the best time as you always have the boobie when needed & they love the motion so they tend to sleep a lot. It's more of a task when you have to pack food & so on!!!
Get out when you feel like it!! I had Charlie in SA where we used to live to be near close friends & family, we then headed back here after just a few wks. So I wanted to show him off, we took him to the local footy match when he was 5days old - he slept most of the time.
