My DD (15 months old) loves playing with things where she can try to fit something back inside something else e.g. pens and pen caps, the medicine syringes you get where she pulls out the plunger and tries to put it back in. It keeps her occupied for ages but they do a worry me a little because they are potentially dangerous if she were to fall on them when walking around / put them in her mouth etc. Particularly the pens!!
Just wondered whether anyone knew of any toys that do a similar thing, or if anyone has any ideas of how to make something safe?!
