Th seat map for their A340 can be found here:

As you can see, it is one Business cabin only, and -although never flown with them- I would not suggest the first row due to the bar in the middle. I guess you (better your toddler) can be bothered by that alot.....
enjoy the trip and let us know how it was..... I am thinking about using them to Asia beginning next year, their prices in J are great....
