Can you ID our Mystery Plant(s)?

My darling 8y daughter EB is in charge of the plants around our front mailbox. (I sooo have a brown thumb - despite my spectacular new veggie garden -ahem- and she is a Master Gardner in training, right GG?). Well this year she planted quite a variety of plants. I would name them if I could but then if I could I would probably not let an 8y plant the most prominent (ie only) flower garden in my yard, right? Anyhoo... half of what she planted is already gone:-( Sniff, Sniff (she has the follow thru of her mom!) But no worries this prolific pink beauty has taken it's place. For weeks we were weeding it out and it kept returning then I had the bright idea to leave it and see if it was a pretty weed -heeheee- perhaps a wildflower? (wishful thinking!) Well ta-da! While we were on vacation it grew like WILD. It literally is spreading like crazy so now we want to know exactly what it is? I emailed a few plant peeps and they have responded with guesses that include Poppy, Ice Plant, Morning Glories but according to Google photos those don't seem spot on so I am going to show you lovely ladies a photo and see who can ID it for us? drop me a comment - if you can ID it, I will mail you a treat for your garden!
