It appears that Louisa might be teething. She wants to put everything in her mouth. Especially if it's cool like a beer bottle.
And she's drooling like a champ. But she's been drooling and gnawing for over a month. And she's not fussy like a typical teething kid.
In fact she's smiling all the time these days and her smile takes over her whole face. Unlike Rock who always led with a frown, this girl will smile away at anyone who crosses her path.
