HotI, congratulations! Sounds like a lovely birth That is rude of your friend. I have found out about a couple of births via people posting on wall's before the parents have a chance. So rude!
Nothing wrong with a big bub. Are either of you very tall? DD2 was 2 pounds heavier than the other two, now at 4.5 months she is exactly the same stats as her sister was at this age.
