How soon is too soon?

Kaicie

So I this is my third pregnancy and I am already hitting the nesting phase. I am only 16 weeks so I feel like it’s too soon to start a hospital bag. I just wanna know I have everything without being over packed. My first I was wwwaayyy under packed and underprepared for what motherhood held for me after he arrived. My second I was over packed but with the wrong things. Do you think I am packing too soon? I know some things I can’t or won’t put in till later but I wanna make sure I have everything practical in there and since my other two were early I have a feeling she will be too.
