Needed to vent! MIL’S disrespect ...

So, I’m a first time mom of NEWLY 5 month old baby girl.

Today my mother in law tried to give her a chocolate chip cookie and I ran to slap

It out of her hand and she proceeded to try and rub a chocolate chip on to my baby’s tongue. She is a 75 year old woman and I don’t know how to deal with the situation without being disrespectful because I am extremely upset.

She thinks because she is 5 months old she can eat what everyone else eats because that’s how she raised her children but I like to go based off of what the doctors say.

I will never leave my daughter with her unattended. She just ruined it for herself.
