Oh gigglewizz - how lovely! Couldn't they tell you at your 20 week?
I wanted to chime in on the gender issue as I relate to so many of you who have posted about it - especially Zoeplankton.
I too have ended up with my heart set on a boy. I think of it as a boy. I want a boy and with my scan on Tuesday, I know it's going to be a massive shock if it's a girl and I may well react just as you have Zoe. Before it was just a preference but with the recent nightmares with my teenage step-daughter, I dread facing that stage with a girl when I'm in my fifties. Boys get a bit monosyllabic but you don't get all this high-maintenance bitch-teen stuff. I really want a boy. I will love a girl with all my heart if one comes out as she will be me & DP's little creation but I will worry x 20 for how her life will be. Ah well - que sera sera and I will learn that what fate gives me is what's meant to be. Would be lying if I didn't say I was praying for a boy right now though.
I should be so silly though - the scan may show up a lot more things to worry about - like squid or perhaps even show I'll need an elective/early induction - heaven knows what those fibroids are up to at the moment! I need to focus more on just hoping that it's healthy and I can incubate it well up until the right time!!
Zoe - I'm also with you and WantanOrange in the dogs/kids 'the behavioural training's not that different' camp. I believe in masses of love, support and positive reinforcement but I'm also strict and believe in authority, respect and firmly enforced rules. Seems so old school these days but DP is not like that and his teen and pre-teen are walking all over him with a massive lack of respect and I warn him that if he doesn't get strict and show them he means business our lives will be pretty miserable in a couple of years.
Symptom wise - I've currently got rather dry skin, which gets itchy if I don't moisturise enough...and it doesn't usually get like that here as the water's so soft. Also having lots of unexplainable tears. Softie/sentimental 'awww that's so lovely' tears usually - happy/touched ones. But thank GOD for waterproof mascara! Also, after moaning about not feeling my LO, now lots of somersaults that feel like 'twisting' and more bubbles and what might be hiccups :). Still not that consistent but getting more often/obvious. HOORAH! 
londonlivvy - my MW was lovely! She didn't even weigh me. She said 'We don't really care about weight - it's not a 'medical' concern'! So I got away with just getting my urine pot dipsticked...no blood...LOTS of chatting and leaflets and a lovely minute or so of listening to the heartbeat (quite fast 150 or something :)). Oh and also my BP was 120/80 so I was well chuffed. Have been worrying big time it was elevated - it felt so over the stressful w'end with DSD1 - red face and headachey/dizzy. Looking forward to my scan on Tuesday and DP is VERY excited. He's getting VERY broody - caught him smiling like a softie at baby-vids on YouTube tonight (awwww :)). Hope the little ninja kicks for him soon...I predict a tear from him at the scan.
Hope you've all got lovely weekends planned. I'm just writing articles and relaxing with DP (and no DSCs!) after a rather manic week. (I promise that's all for now!
).
