Why am I worried about Elena's appointment on Tuesday? It's just a simple procedure that shouldn't take long. It'll help her eat better and help her latch but why am I worried? I feel like I shouldn't be as worried as I am..... Can anyone ease my mind on this please? Maybe someone who's baby has went through it. She has a lip tie and they are going to correct it. But it still worries me.
