In my experience, I did have time for walks. I would try to get out for a decent walk every day. Most days it happened, occassionally it didnt happen. She used to just fall asleep in the pram for most of the walk and then wake up the second the pram stopped moving! Some days I was just soooo tired (cause she was waking every 2 hours at night until she was 10 months old) so sometimes I was just such a zombie. But now that I think about it, those walks actually made me feel better on those zombie days.
