I'm more impressed with my SIL than Kate. SIL has managed to get her pre baby body back with in 6 months or so.
Size 8, 5'6 ish - she has no chef, nanny, personal trainer, gym or pool in her house, or staff to do the shopping, housework and sort out the direct debits/laundry/sicky baby-grows. Nor does she have the eyes of the world on her as an incentive to look good.
Frankly, given her shape pre birth and the fact that she lives in a palace, i would have been astounded to see Kate looking dumpy at this stage, not the other way around.
We cant compare our lives (and it's consequences) with theirs.
