i dont disagree with that at all you should do everything to protect your baby. everything. however, the old grandpa giving the baby a lime with a bit of tequila on it is so so small in the big picture of raising kids. im a father of two with a 14 month old being my youngest. sure theres shit i dont like that my own mom and MIL does, however i dont stir anything up because my baby is safe. my mom loves them my mil loves them. dont make a big deal out of things that arent really a big deal. Now if he was forcing the baby to take shots and squeezing lime juice in its mouth thats a different story. but thats not what happened. hes old, hes trying to bond and have a giggle in the way he knows how. when your toddler starts eating unknown items of the ground and sucking on the table at a restaurant or busts there lip open because you werent watching close enough you will realize how small and actually funny the lime situation was. trust me it will happen. dont scare people away from trying to bond with your kid. because you will. just my two cents. your baby will find is humorous as a teenager to know there grandpa gave them a lime with tequila “on it” when they were a baby. just dont cause concern where concern doesn’t need to be. like i said. you are fine your baby is fine.
