I second everything Longratia has said... if you can do without having pasta, all the better... and, as for the bread, he does say not to go over 40g (which is about 1 slice of plastic supermarket brown bread or two tiny ones of "pain complet" over here which he recommends from the boulangerie rather than supermarket). It's all carbs of course but the idea in phase 3 is to phase them in slowly but if you're just having a little holiday adventure, if you can avoid it, great! White bread/baguette no way!
After, as Longratia says, theoretically you'd need to drop back into 2 to 3 PPs, and you will probably have gained some weight with your carbs, but with your baby plans, perhaps you could eat healthily without ketosis.
