Sorry, I write in Chinese but cannot be displayed.
Would a vest top (with zip infont) be better?? since two
pieces would be easier for going to wash room, body type (one piece) might be warmer but very difficult for kids to "wewe"!!
I need to buy one for my boy too. But it is quite
expensive buying in Standford. It costs around $300 for
a vest. I will find somewhere cheaper.
