If only the world would change so all your selfish needs are met.
This goes both ways. What you perceive as a business person's "selfish need" to them is important - just as important as your toddler's need to toddle. Neither of you is right about the other, but neither of you is wrong. Compromise and give and take.
No one is saying that children should be packed up and kept out of sight. People are just saying that there's ways and means to teach your children to walk, and to walk in public, without being a disruption and a hazard - which is, after all, essentially what you're trying to teach them, in spite of all this outraged rhetoric about toddlers having rights. In dismissing and pooh-poohing the rushing adult's needs in favor of your child doing something that they could do somewhere that isn't in people's ways, consider that you are being just as selfish as you think they are.
No consideration whatsoever what this means to the development of the toddler and how they will be in society, if they are made to feel they are in everybody elses way!
And what if they are in everybody else's way? Because sometimes, that is legitimately the issue. What then? Yes, your toddlers have rights. Yes, they're people. But the rushing business people are people too. I don't think they have the right to tell you that your toddlers can't be out in public, of course they don't! But neither do I think parents of toddlers have the right to tell other people that their lives have to be put on hold while your child toddles in their way, if/when they can be guided - or taken - elsewhere. You don't have the right to tell someone "what you're rushing to do isn't as important as letting little Rufus find his legs". You don't know. You have no way of knowing what that person is rushing to do. It isn't important to you, but it's important to them - as important as raising little Rufus is to you, perhaps.
Everyone who is saying that toddlers have rights, well, I think that's true to a point, but I don't think they have the right to be prioritized over everything and everyone else, when we as a society should be teaching them that everyone has to compromise and give and take in order to keep things running smoothly and pleasantly.
