Safe essential oils to use around newborn?

C

I’ve read not to diffuse around babies until 6 months, but is that in the house or in the room that the baby is in? She’s never in our room and I want to use our diffuser to get the dog smell out. If it’s not safe I obviously won’t, but just wondering what the general guidelines are. They aren’t “good quality” ones, just basic oils from Amazon and Walmart. I don’t use them therapeutically, just to freshen up the room.

Thanks!
