OMG...I saw them and had to hold back...I'm a cow freak and have them all over the place...rofl.
As for bubs size clothes, I had the same dilemma you were having. I ended up buying an 8 piece outfit (so has pants, shirt, long jumpsuit, short jumpsuit, hat, booties, jacket and something else...lol) and a couple of long sleeved short leg jumpsuits and a bonds wondersuit all in 0000. I had 000 which have been given to me but I haven't packed any of those but if I need then DH can bring to hospital after. I soooo couldn't work it out but as a rough guide the bonds clothes say 3kg on their 0000 size and 6kg on 000! I got given 000 singlets but haven't bought smaller cos the bottom can be folded up or tucked in anyway ;)
