Help Switching Days and Nights

Hi Everyone,

Sorry if I posted this already. Looking for some advice on how to set up a routine to help my little become aware of days and nights. She is just shy of 3 wks so I know not to overdo it and expect too much. Just trying to level out her naps right now. She can sleep between 2-3 hours, sometimes 4, during the day and then night she is awake. She feeds well during the day, between 2-3 oz every 2 to 3 hours. I do my best to increase time awake before feeding if she isn't too fussy, so I do bicycle kicks for gas after each changing, tummy time, and then feed. Just to try to have her understand awake time. Blinds are open, tv is on, and I'm doing chores as I can (because I need to nap too. Haha) at night I keep everything quiet, only have a nightlight on in the room.

It is really hard because while I'm married, I'm basically doing this alone as my husband works 2 jobs so he is gone 16 hours a day and when he comes home he is sleeping or eating.

I'd appreciate any suggestions, but please I ask they be realistic. I posted on a Facebook group and someone told me I need to bathe her in lavender every night and have night time essential oils misting in the air. ...my pediatrician said she's only supposed to have a bath 3 times a week since she is so little.

Thank you all for putting up with this FTM. I am struggling!
