Expensive Toy vs Cheap Toy

I know exactly why now the well known toy manufacturers make it so hard to get batteries in and out of their toys. I caught Madelyn today with a battery in her mouth. She had taken the back off of a cheap toy and pulled the batteries out and had one in her mouth. Yes, I freaked out. The battery was not chewed but this could have been really bad. This toy now has a place in the trash can. I'll remember this next time I'm searching for an itty bitty screwdriver to take a back off to replace batteries.
