I agree with the other, sounds very normal to me. Get ready for the 'poosplosion' though!
O we're ready for the poosplosion... DS1's first one coincided with a long car trip and there was absolutely nothing open at the time so we had to unpack the back of the car and change him as best we could on the side of the road! Needless to say we take extra cloth squares, lots of wipes and extra clothes with us everywhere with DS2. This time it's the chucking that's caught us out - I'm not used to needing a whole extra outfit for myself! I need a bigger bag! lol
