Sounds like things are going wonderfully with Ivy, and I'm really glad to hear that. It sounds as if her development is going according to plan, including her stages of EHK. My one suggestion is that if the lac-hydrin isn't doing any good and is causing her pain you should probably drop it. I've gone through so many lotions in my lifetime it is just a little ridiculous, but that rule of thumb has kept me from getting into too much trouble. After all, what's the point of suffering if there's not benefit to it?
Keep up the good work!
Live life like you mean it.
