I have meet babies before, and maybe one of them is yours, who start teething at 4 months. Kai is now ten months and has just one tooth, but I swear he has been teething FOREVER! Just one tooth to show for all of that work but I am now getting a sweet reward; laughter and lots of it. Maybe it is the wild animal in me, I don't know, but ever since he was brand new I would tell Kai how much I love him and then gently "roar" in his ear to reassure him of how strong my love is. Knowing this you wouldn't think it odd that Kai now does it too, the funny thing is that Kai didn't start "roaring" until he got his one tooth. My sweet little baby who used to coo and cuddle with me is now a BIG, scary, one toothed monster who "ROARS" really loud while chasing me around the house, making sure I know that I am loved!!! Needless to say Kai's new nick name is one tooth and every one he meets he proudly shows them his one tooth with a "ROAR". Mommy LOVES you Kai!!!
