Ladies!! Dating a single mom?

I am trying to get to know a single mom. We talk on the phone just a bit, text some. She doesn't always return my calls/texts. I sent her flowers to her work a couple weeks ago and you would of thought I gave her a million dollars. I had a dinner date set up, but she had to cancel for legit reasons. I thought of dropping off on her front steps a box of little gifts like bubbles, sidewalk chalk and a few other things that her and her young child can play with? Is this too much? Thanks!
