Hi ladies, your responses are so helpful! I too am expecting twins in August.
3rd Time Lucky we sound so similar ... having major issues with accepting that with a twin pregnancy I am no longer in control. I keep telling myself "You are not driving the bus, you are just taking care of the cargo".

I too was wondering about size clothes.
I've been told to have a few 5x0 outfits for when they are first born, but they will probably get more 'wear' out of 4x0 clothes. Obviously if our twins arrive really early, then everything changes and they'll be in premmie clothes but I figure if they are really early they will be in NICU or SCN so clothes not really needed??

Friends have had 6lb babies and all of them started out in 5x0 clothes. Being that our twins will be born in Winter am guessing a bit bigger wondersuit/growsuit/all-in-ones won't really matter as the bubs will be wrapped most of the time so no one will notice the legs/feet being long.
DD was 7lb born, but she was quite long so she went straight into 4x0 for the length - big around the waist.
