Fellow stay at home moms!

Hi ladies, my first baby is due in 4 weeks and I am going to be a full time stay at home mom for the first time. Does anyone have any advice on how to keep yourself sane and entertained? What did you do to pass the time and stay happy? I can only watch so much Netflix haha. I just feel like I need to make a routine and find constructive things to do. Let me know what you SAHM's do! Thanks!
