FWIW, I wrote to Carolyn Hax and asked for her take on saying anything about gifts on an invitation. She said she knows the old rule that it's rude to say anything, even no gifts, but that people seem to like helpful information such as "no gifts" so it's fine. I'm a rule follower but this rule just needs to die. I'm not suggesting people demand you provide gifts for a particular cause, but saying no gifts has got to be ok.
So, OP, I'd say no gifts and just mention to friends that maybe you can do a toy swap or something, outside the birthday context.
