It is a terrible nickname, but it makes your dad smile, so....

Im sorry.. maybe you could make some suggestions to your father.. say.. dad.. maybe instead of that we can call it.. jug juice.. or titty treat.. i think he'll be receptive. 🤗

Your dad can stop calling him that when he gets older. For now I agree with your baby :) it is cute.

sure there is no harm in it and your dad means this in it fondest way . but if you find it offensive -perhaps you should have a word [firestarter]

He will invent many new nick names over time, it won't always be Milkbreath. Let Granddad express his love, funny names are part of the deal.👍

Babies don’t know what you are saying, but they do pick up on tones.

Your baby probably smiles because your dad is saying it lovingly and being silly with him

Babies don’t listen to the words they can hear the tones of the voice if your dad is doing it in the cheerful playful way that’s all the baby cares about

I used to laugh at my niece and say

FAT BaBY

And she would giggle!

I stopped when she was two

Sounds like an insult from Skyrim, “milk drinker!”

Bet your dad changes the nick name

Maybe not, but I imagine when he’s older, your father will no longer use it. It wouldn’t be relevant as a nickname for an older child. The baby smiles because what he’s hearing is the love behind it, not the words. 😊

Nah it's silly and he knows the baby can't understand it.
