Baby Tip for Teething - Bath Toys

I have a 9 month old that just got her lower incisors and has been biting everything! I have given her teething rings but she only seems mildly interested by them. One thing that I happened to notice works well though, which makes perfect sense - RUBBER BATH TOYS! She loves chewing on the little rubber animals and it seems to calm her down. So, if you haven't already thought of this, just a little tip!
