Query: My 5 month old son pulled this off after two minutes.

After reading other reviews I thought I'd finally found something that my son couldn't remove. Sadly, he pulled it off after two minutes. It's a very hard toy, so he bonked his head in the process. Then he got it stuck in his lap and screamed.My other problem with this toy is that it is very tall and bulky.
