After school. Is it ok to just say "come and pick up X at 5/530pm?" ie before tea? Or will the parents automatically assume their kids will be eating with us? I'm trying to psych myself up for more playdates next term - I find the whole thing a bit stressful which I know is ridiculous- but the idea of having to cook for another kid on top of my 5yo and their 2yo monster food throwing sibling really puts me off!
