Today is hard

Today is just hard. I'm desperately needing "me" time. My baby smacked her forehead against the dresser (I'm trying to just remind myself that babies bump their heads and to forgive myself for turning my back for a second) then she destroyed a board book in her pack and play and now I know, no books unsupervised. I don't think ingesting cardboard is dangerous? There is none stuck in her mouth I checked.

I love her so much but I am so tired today and I feel guilty being frustrated.
