Re: stretch marks
I have been pretty lucky so far, fingers crossed it stays that way till she pops out in a few weeks time. What I have been warned though is that you should not lose weight too quickly if you want to avoid creating stretch marks from that. I always thought you would just get them when you gain weight, but apparently if you lose the baby weight too quickly you can get them then as well.
As to what to do about any you already have, the only help I can offer is that time really does help them to fade. When my friend had her baby she had really angry red looking stretch marks all over her belly. By the time her son was one they looked nothing near as bad as they had been. They had faded and gone all pale and silvery. I hope that is some consolation.
PS - they are the marks of being a mummy, so try and embrace them as part of the whole creating process.
Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree today.
