It's an issue.

Have I ever mentioned that our little Berlyn is an adamant thumb sucker.  Well, it started with the binkie.  She would hoard them around the house.  She'd have one in her mouth and one in her hand.  I'm actually surprised that she learned to talk as early as she did, because it was a rare occasion to see her mouth binkie-less.  At two, we took the beloved 'wub-a-nub' (the binkies all had tiny stuffed animals sewed to them) away.  Never having sucked her thumb a day in her life, she popped that appendage in her mouth and formed a habit.  At the dinner table, we had to tell her to take out her thumb to take a bite.  If we were talking to her, we had to coax her to take the thumb out to answer us promptly.  Honestly.  She's passionate about what she loves, and she LOVES her thumb.  Finally, at three, we had to do something.  I bought some nail paint called STOP to put on her fingers.  The taste is absolutely horrid.  I've tried it.  To our dismay, Berlyn had no problems letting us coat her nails.  However... she will purposefully sit next to Talullah and suck on HER thumb.  I'm not kidding.  Has anyone else ever heard of a child doing this?  The bright side of the matter, we have full faith that this character trait that God has blessed Berlyn with, DETERMINATION, will benefit her in so many ways when she grows up.  When she puts her mind to something, watch out world.  Until she grows up and can utilize this blessing, we have got to find a way to break this thumb thing.  We've started painting Talullah's nails, too.  Lord have mercy if we decide to give the baby-to-be a binkie...
