Any essential oil users??

So my baby girl is 6 weeks old, I love using essential oils around the house but haven’t since she was born. I’ve tried looking it up, and as with everything else with google I’ve gotten very conflicting advice on when I can start diffusing it in the house again. I really like using peppermint and eucalyptus, which I know can be strong, especially for a newborn. I’m sure there are some oils I can use before others (maybe lemon, or lavender?) Any advice? I tried looking for a group specific to essential oils, but none of them seem to be active anymore.
