Reddit reviews The Berenstain Bears and the Bad Habit

They make bitter, but safe, polishes you can paint on the nails to deter biters.

Also, the Berenstain Bears have a relevant book you can read together.

Also, be sure to file, not clip, any ridges or uneven tips. I'm a biter and I find having even, smooth surfaces discourages me.

My Dad just read me this book and it stopped me forever. Not my sister though lol.

IDC about bitten nails and think they are kind of cute. Big hands, especially bigger than mine, I just cannot deal with lmao. It's so unreasonable but a lot of it revolves around just not wanting big hands on my dick. Also, hand tattoos for similar reasons. One of my instagram crushes tattooed her hand and I was unreasonably upset over it, unfollowed.

Get the one for birds. Birds have a much lower threshhold for toxic products than nearly anything else, and will probably be safe for you.

If you die, have your mom message me for a profound and sincere apology. ;)

(seriously, ask your doctor first if you are concerned about it)

(edit - there is something similar made for thumbsucking babies, too)

2nd edit -

You shouldn't have said anything. Now I am having too much fun with this: http://www.amazon.com/The-Berenstain-Bears-Bad-Habit/dp/0394873408/ref=pd_sim_bt_2?ie=UTF8&refRID=0AQR7JACFG86P6XCJ846
