Comfy they may be, but I couldn't wait to be out of mine and get back to normal, "proper" clothes. I can't wear an elasticated waist forever!
I wore my trusty Top shop Leigh maternity trousers for the last time the day I went into labour, and then after the birth I wore leggings/yoga trousers until I could fit back into my old jeans.
It might sound daft, but the mat jeans just hid the fact that I still had - and have - a huge mummy tummy. DD is four weeks old now and I think if I were still in the maternity jeans I wouldn't have the same need to get the weight off, IYSWIM?
And normal jeans are as comfy if they fit properly, right?
