For what it's worth I don't think you're wrong with your choice, or suspension is useless per se. It's just that IMO presenting some features or accessories -invariably found on expensive bikes - as essential is basically suggesting that if you cannot afford them you can't carry your child. And that I think should be challenged, because not everyone can spend that sort of money, but all parents should be encouraged to ride with their kids, if they can safely do so.
