I don't think its essential to stay at home, just avoiding trips out all the time.
My life doesn't stop after having a baby, there is still shopping to do, other kids to take to preschool etc. But I do think trips to the shops, visiting friends etc just for the hell of it is a bit unfair on bubs. Like I said its tireing to be out & about, in & out of the car, pram etc. Being passed around for a cuddle etc. I definately notice that my babies have been more cranky & unsettled if they have had a busy day. I try & stay home for acouple of days in a row if I have had to go out, like shopping.

All I am saying is it should be limited.
