Answers from Stay-At-Home Mothers; And Soon-To-Be Mothers.

Hello ladies;
I am going out of my mind; what do y'all do to keep busy in the winter months when the snow is on the ground? 
Spring time I'll be gardening and being outside landscaping, however, what do Stay-at-home mothers do all day? 
My fiancé got a new job and we relocated, I am currently not working (which I would like too) but cannot find anything that will be flexible enough in the summer when his daughters from a previous woman will be out here too keep me busy, and spending the summer with us. 
What do y'all do to keep busy, and what are some tips for me?
-thank you. ☺️
