Now I need to make it clear that this is most definitely not how the access rules work and success is dependent on the leniency of the lounge dragons. I would suggest to try your luck at the Air Canada Maple Leaf Lounge as staff there seems to be a little more relaxed and less rules obsessed compared to the LH dragons. But if you so wish there are about three LH lounges in addition to the AC one that you could try your luck at in the non-schengen area. There are even more in the schengen area.

The other option would be to buy lounge passes for the third and potentially (depending on the age of the child) the fourth guest.
