DS is nearly 5 months old and I thought it would be nice to make him a simple treasure basket. The creche he's going into at 12 months use them (had never heard of them before) and it sounds like a good idea.
He likes to grab things and examine/put in his mouth.
What sort of things could I put in it? I'd just use a medium sized plastic box to put them in. Should I use household items only or can I also use twigs/things from outside etc?
