Hey all. Need some advice here. Travelling LHR to SYD in November on BA club suite with wife and 2 kids ( 3yo and 8 months)

I have a seat for everybody as we're using a companion voucher. Obviously infant won't be able to be seated but what is the best seating arrangement for parents to service the kids?

4 in a row? Or

2 x 2?

Any body with experience on this who can help?

Thanks
