Will there come a day when I am not so nervous?

Iz has a doctor's appointment tomorrow. Just her nine month well check. Height, weight, milestone checklist. No biggie, right? Then why do I fell so sick to my stomach? Why am I waiting for the bad news? Why am I so nervous about a perfectly ordinary well baby visit? I wonder if the day will come when taking her to a doctor is no big deal, just another stop along the way? Or will each visit bring that breathless feeling? Will she be fifty years old and I wait by the phone, worried, until she calls me and says she got another ok? (or at least I hope she wants to call me.....I have a feeling I will worry about this daughter of mine and her heart til the day I die.....)
