Dd (nearly 5) just came through to the kitchen saying she thought she was going to be sick. Gave her a bowl, sent her to dh, because she thought she needed to sit on a lap. A few minutes later she and I were alone and she confessed to having swallowed one of the little balls from ds's geomag set. How many times have we told her off for putting them in her mouth in the past couple of days?!
I'm inclined to let nature take its course, being that kind of parent in general.
What would you do?
