nellnell, so far I haven't had to get in and out of the car anywhere particularly busy. My DS1 is a real pain about getting in his pram at times (he thinks he can walk everywhere but it takes forever ) so I make sure I have him strapped in before I even contemplate getting bubs out. Otherwise I haven't had any real issues so far.
I can imagine that it would get to be a bit much having girl clothes and boy clothes at the same time. Seems a shame to get rid of them though, especially if you are wanting another one down the track. That is one plus of having another boy... Edward will get to be the hand me down kid.

2cb, I am not feeling too bad about my size, I am only a 14 at the moment, normally a 12, it is more that it is really annoying having nothing that fits properly. I put on over 20kg with DS1 and felt pretty ordinary after I had him. It still didn't take very long to get rid of it though. It will feel really satisfying when you get to where you want to be!
