I'm not flexible. we have five and everyone knows not to mess with mommys schedule. I plan 40 minutes to get littles ready for anything (2 and 10 mo) I do any errends first thing in the mornings and am always home by 11 am for lunch and bed . I do a play group once a week so they get social interaction and I do meal planning and prep on sunday so I don't have littles in the way. I get up two hours earlier than littles to drink coffee, start any meal for day and start chores.
I found structure is the key for me getting anything done in our family of seven
