Wow Raven, 7.5kg, what big babies! (I'm guessing you mean 7lb 5oz? )

My boys were (DS1) 3.75kg and (DS2) 4.03kg and both started out in 0000's, but didn't last very long in them. Like Raven said, 000's were just too big at the start. So I would only buy a few 0000's. And like Nelle said, the Bonds wondersuits are usually a size smaller than what is on the label, so their 000's would be perfect for a newborn
