Your translation is essentially correct.
A nappy is a diaper, a dummy is a pacifier, or “binkie”
A Ten P piece is smaller than it used to be and is about the size of a knickel.
I know someone who had a child this premature and about the same size some 12 years ago. The kid grew up to be a normal healthy child.
Thanks for the translation! It’s funny that it’s all English, but it’s not the same English. :-) Of course, down here we speak English but sometimes people still need a translator.
I’m happy the little one is doing good! Great story.
