Do not disrespect mothers

So I am a clean person and make sure my phone is disinfected along with door knobs and handles and light switches and remotes.

Baby and I were at the in laws and my SIL was holding the baby. I had forgotten the binky and so my SIL just stuck her finger in his mouth. Like what the heck.

She said, “don’t worry I just got out of the shower so I’m clean.”

Her phone was right next to her and I know she touched it so I said, “yes but was your phone clean when you touched it then put your finger in his mouth?”

She rolls her eyes and says yes even though I know she didn’t clean it. Her finger was already in his mouth at that point so I didn’t say anything else.

She has disrespected me before and made me feel bad about being a clean person, like the baby won’t build any immunity. I’m all for building immunity but you leave that to me and how I choose to do it. Don’t be disrespectful and be a know it all.
