Air Europa hates children

Air Europa = They hate families. Worst airline experience I had to make so far --> Air Europa wanted to let a three year old child sit alone on the plane!
1. the online checkin opened 48h before departure. Within 10 minutes I checked in. But I was immediately put on the waiting list/standby. This alone is not okay, because the flight was already booked months ago.
2. the lady at the hotline then told me that she can at least book me on 3 seats. However, my three-year-old (!) Daughter can not sit with her parents!
3. at the check-in counter at the airport, I was told again after long discussions that the 3-year-old child must sit alone.
4. at the gate I was again told by the staff that nothing could be done and the three-year-old girl must sit alone. Only after long discussions, a solution was then found with the boarding staff that at least one parent can sit with the child. This behavior towards children is absolutely disgusting and I have never experienced such a behavior towards families with any other airline. A three-year-old child should be supported by the airline, his fears should be taken away. In no way should a girl at this age be forced to sit alone on a flight!
