We'd love to be able to provide a shoulder for a little one to rest their head on but we also have anything from 100 - 400 other people clamouring for our attention. We don't have the time or resources to do this.
Sorry, Jetset, but I can't believe you really are crew...if you are, then you've forgotten your training.
Every time we fly with our kids, the crew are more than happy to to see them and treat our children as individuals.
