Aren't you still BF? I'd say it's normal then! And by the look of you just after the birth of your DD at the last meet up, I don't think you have anything to worry about

Ive done a lot of dieting over the years though and my thing is to 1. not have too much junk in the house or if the junk is required, it's packaged up and saved for guests, BBQs, etc (eg chips, dip, etc) and 2. allow myself a treat once a day but only one. I also have healthier things to snack on like rice crackers, Chinese rice crackers, healthy dips and veggie sticks, etc. That helps.
