For dandelions in the lawn either you dig them out or you use a selective lawn weedkiller which kills weeds, not grass. But keep your little one off it until it's been rained on. For the paving glyphosate weed killer is best. It takes a little time before you see it work though as it has to be taken down through the leaves into the roots. It doesn't affect the soil, only the leaves it has touched. When it's dry on the leaves I think it's harmless to all but the plant.
Bindweed in the hedge is tricky. You will have to kepp pulling it out. Or try and tease it out and dab leaves with glyphosate.
Horsetail has long roots and the only way is to spray is with glyphosate. (No, I don't work for the company!) Most other weedkillers have been banned now so there isn't much other choice!
