baby oil, vaseline, unscented lotion are all great just remember if you use any of those clean the nipple off before feeding baby because those are all petroleum products and petroleum is toxic if ingested!
Use baby oil!! It dries fast and it doesn’t keep its smell
I use the same lotion I put on my baby 😆 I don't know if that's good for the smell or not but it hasn't seemed to be an issue yet. it's the aveeno baby lavender lotion
