Swearing

So my loving husband was reading to our sweet little daughter yesterday. When he said "there's a boat in Dora's backpack". When our daughter heard this she exclaimed "What the FUCK a BOAT!" Of course my husband instantly started laughing and i was frozen not knowing wether to be mad she said it or proud she used ut right. Well i just ignored it until this morning when she looked at her dad and pointed "bish". I assume she was trying to say bitch which again she used it somewhat right but not sure how to deal with it. Honestly I don't want her to grow up thing words have power that they don't but I also don't want her to be hurtful with what she says. So i've let my husband take over this because i have no idea how to teach her that intent is what's important not the word itself.
