Pennie I agree, so many times you think, oh my one doesn't do that... But it's lovely to celebrate the things they do.
My DSis's baby sleeps well, has put on weight, is alert and happy and she had a natural birth too - I had been trying not to have uncharitable feelings about this as things were so hard with L, I don't begrudge her but you can't help comparing sometimes. She said her NCT group are really unfriendly and arsey about her good fortune but she can't help it, unless she lies to them she feels like they don't want her around.
That is so interesting about M being 2 years old in embryo terms, my friend had IVF twins last year and they were actually frozen ten years ago (she'd had several attempts) and are possibly even from different batches so could be different 'ages' in that sense. Personally I would like to keep my options open, so would want to pay for the continued storage, but it is a completely personal decision of course.
