Im sorry I also can't help with names, I had enough trouble picking Luca's name even then people kept asking why did I pick a boys name for a girl.
I too wouldn't buy to many 0000. Jackson is still wearing alot of 0000 clothing and he is neally 7 months old but he was only 650g when born and is very slow in the growing department. Luca who was a lot bigger especially when they came home outgrew her 0000 clothes very fast. Some of them never look worn. So getting too many 0000 can be a bit of a waste. I would just buy a couple of things but then go for the bigger size. They will only grow into them
