I got my nephew a size 3 (he has just gone 2 a couple of months ago) all cotton (but thick double layers) Snugtime sleepsuit in David Jones about 2 weeks ago on sale for $20. They have arms and legs in them and zip up. I bought 2 for my DD one with arms and one without. Then you can layer clothes underneath to suit the weather. I got the armless one in Myer for $35- that's the normal price. I think they're great!
