Like alot of people have pointed out, there are many factors to consider, but going for a walk is definitely doable! With DS1, I had had stitches because of an episiotomy, but I used to put him in the pram after a feed and at least walk around the block (a couple of times a day, weather permitting) After a month or so, I was taking longer walks (I didn't have a car, so walking was my only form of transport!) and when our mother's group started meeting at each other's places and cafes etc (as opposed to the ECH centre) I would always walk there (or catch a train if it wasn't local!)

Now, after #4, the best I can manage is walking DS1 (now 7.5) to the bus stop each morning with #4 in the pram, #3 in the attached toddler seat and DD walking at a typical 4yo pace!! I just physically don't have the time anymore!

ETA but if you are used to being active and out and about, it shouldn't be a problem to get back into the swing of things!

And Tannis, I agree, coffee is quite easy! Even with 4 (provided the oldest 3 have a drink and a donut as well!)
