2 lbs is very good, also given your height! (I am short too, so I know how it feels ^^)
you have experience maintaining your weight, this is awesome! Just imagine, the faster you lose it the more difficult it gets to maintain. and 2 lbs are at the border of "rapid loss" for us shorties.
If you go on like this you will be "through" in about 11 weeks. that is not even 3 months. you will have it all gone in october... just think of an event in novemner where you will go with your perfect weight. a halloween costume maybe?
Give your body the time. to really lose radically more you either have to starve yourself or work out half the day every day, which both doesnt sound too funny, does it? . Your body is a good one and losing at a fair speed.
Also remember your body had more to work with as you lost that 60 lbs back then. So it of course would lose faster, since you carried all that weight along for all day, which made it burn more. imagine you would have to have a 60 lb backpack you have to drag along day in, day out. that is why it maybe was able to lose more back then.
anyhow, congrats on the maintenance and congrats on the fast loss for your weight and height. hang in there, we are here for you
