This has been appearing in my garden the last couple of years, you may not have to worry about looking after it as apparently it selfseeds freely and is now popping up everywhere, including the lawn...I read that it can spread into lawns which are ‘growing poorly’ so I’m taking it personally 😂
I believe it is shining cranesbill, geranium lucidum. Not hairy like doves-foot, but smooth and shiny. Pretty, and easy to pull up after flowering if you don't want too many. (Similar to forget-me-nots in this respect.)
