How often do you get out of the house during the week?

I am a recently turned SAHM and have a 2 1/2 year old and an almost 8 month old.  I'm gradually getting out of the house more and more with both of them, but it honestly puts me on edge every time I do.  I think I'm just plain scared of the unexpected, especially with my daughter going through this terrible twos stage and dropping to the ground in a tantrum for whatever random reason. I know it's healthy to get out of the house some, but wondering how many times I should aim for during a given week. 😊
