I had two kids -- one 9 years ago and one 5 years ago -- unfortunately I'm still trying to lose the weight
I think it's harder just due to the creativity you have to show to get some exercise in, the lack of sleep and the quick meals you sometimes need to make.
But, like you said -- the little peanut made it all worth it. I wouldn't trade my two guys for the 100 pounds I have to lose!! (Not that they caused the whole 100 -- just a mear 40 of it
)
Take care of yourself and you will lose the weight -- just think by the time your baby is walking you could be close to your goal!!
