I'm going to be traveling with an 18 month old from LAX-AMS on KLM in business and had initially booked a seat for for 18 month, however I'm now finding out that KLM definitively does not permit car seats in business for that flight and am getting conflicting information from the airline about if I can use the CARES harness. Is my best bet to just have my daughter as a lap baby? I was hoping to utilize the lie flats for her so that she could sleep on the flight, but I also don't want to put her in an unsafe position.
