Confuzzled

Hrmmm... Just been invited to a wedding at the end of april 2012...in sydney, we really want to go because its one of hubbies good friends and prolly one of the last few weddings we will ever be invited to.. So humph?! Go or no go? Im very reluctant to travel with such a young baby (omg where do i begin to pack?! For all of us?!) plus who is going to baby sit the baby while we r at the wedding? Argh... Seems all too hard, do i even have a dress i can fit into? But i still really want to go, sight see sydney n eat lots n lots of yummy food, wot do u think? xo
