I've never worried about poisonous plants when the grandkids come to stay, but I have said to them never to put anything in their mouths unless I've told them it's OK, as some plants could make them sick. I think in most cases that's what would happen, rather than the child just dropping dead. They seem fine about this, but I let them eat raspberries, strawberries and tomatoes straight from the plants, which is fun for them. The age at which they just just put everything in their mouths (from crawling stage up to about 18 months or two years) is not an age when you'd leave them unsupervised to crawl around your flower beds, and by the time they are old enough to run off behind your back, they're also old enough to follow simple rules.
The one plant I would be wary of is yew, which is not commonly found in gardens. The berries look really pretty and appealing but the seeds inside them are very poisonous. My nephew had to be admitted to hospital after eating some in a park, and at one stage they were not sure they would be able to save him. He did make a complete recovery.
