I did it last year after reading about it here and got everything I asked for.
A baby: Asked to get pregnant September and found out I was pregnant in November. We had been trying for 2 years before that.
Better house: I asked to be happier in my home. We rent and the house we had was very dark and needed lots of repairs which the useless landlord didn't bother with.
We got a letter in October to say that the house was being repossessed as useless LL hadn't been paying the mortgage so rather than go through all the fuss of that we gave our notice, packed up and moved in with my parents to look for a new house.
We moved into the most incredible house in February, in the area we have always wanted. Our new LLs are a wonderful couple and couldn't be more helpful, the husband even cuts the grass for us as he enjoys gardening! It's bright and happy and my DS loves it here. I feel like this is much more my home than the other house and I'm happy here.
Lost weight: I am thinner now DS is 5 weeks old than I was when I got pregnant. I have no idea how as I had a curry addiction for 5 months of my pregnancy. :o
I know this stuff probably would have happened regardless of my asking however, I'm going to keep asking. Just in case there is anything to this cosmic ordering after all. I'm also going to try the yellow balloon thing.
