One pediatrician has taken Ethan's case and another (who has been a pediatrician in Abbotsford for a lot of years) has noted a link between these kinds of tremors and breast feeding (I wonder what THAT says!), intimating that once Ethan is no longer breast fed, the tremors may well disappear. We shall keep our fingers crossed.
All in all, I think he'll be fine and I thank you so much for your kind comments, concern and prayers. So does Kristen. If there are any developments, I will definitely let you know.
You are all so appreciated; you have no idea how much your support is felt... thank you from the bottom of my heart.
