Weed identification help needed in Ontario Canada!

[Rhonda Buchner]

These three weeds have popped up in my flowerbed and I would like to know what they are and whether or not they are safe for my baby Hermann's. Any help would be much appreciated!
I'm in Ontario Canada.

I cAnt tell u myself, but if you can try using a plant identification app, it helps a lot.
