Hi ML, you are not alone in being unhappy with your appearance! I find that exclusion diets (cutting something out of your diet completely) are too hard to maintain. I end up craving whatever it is I have excluded! I work on the theory of 'everything in moderation' and try to control my portion sizes, which tend to be far too big.
Exercise is difficult with a little one, you're right that they are unlikely to give you uninterrupted time for exercise. If you would consider it, may gyms these days have childcare facilities where your DD would be cared for on site, very near to where you are and the staff will come to get you if she needs you. Otherwise, I would suggest putting her in the pram and just getting out and about and walking. There are plenty of good running prams on the market if you like to run.
As for the smoking, as an ex smoker I would have to say 'don't doooo it!!!'. You've done the hard yards, don't take it up again! Maybe replace the fags with something else you like to do, such a taking a walk, eating an apple, chewing some gum...
