Wow - the difference in the pics is amazing! - you have done so well!
I am in a similar place that you are now in your journey and your pics inspire me... as does when my kids notice I am being more active with them (your son must be enjoying his new 'run about' mummy!)
I find that my biggest problem at the moment is finding clothes cheaply for this in between stage - you don't want to pay heaps for your clothes because you know you wont use them long but you still want to look hot! I have found that ebay is my friend and I am loving the city chic jeans from star*of*oz - have you found that jeans fit so much better now that you have dropped your weight. When I was bigger I could never find the right pair of jeans... now I am having a hard time saying no to myself when I see new clothes/jeans that I feel like I need! Lucky I have found a way to buy the things I crave (my new way of having my cake and eating it too hehe).
Keep on your journey
