It is doable. I get mad at negative people who say "ohhh, you'll never have time for exercise/ coffee/ reading/ life etc" after baby because its not true. Yes, babies change your life hugely and each day is a new adventure. But you DO eventually find some sort of rythym and a way of managing things to get some of the stuff you want to do done.

Also, just wanted to second a pp who mentioned walking around shopping centres. Often the weather is not great for walking outside (I am pretty picky), and I go to the mall most days and walk around. My DS loves it because of all the new sights and it gets me out and walking a bit!
