I am going to pick up some gourds and pumpkins tomorrow to put out for my kids to play with. I have quite a few under twos so I think that they will like them and they are not a choking hazard. On a side note, when I worked at the centre in the infant room. we made sensory bottles out of small plastic pop bottles. We put everything in them, water and sparkles, coloured oil and water, rice, etc. We sealed them with extra strong tape.
