Haven't had time to read everyone's replies, but here's my thoughts:

1)  I tried every test under the sun - the ring test, the cravings test, the way it was sitting, what you ate before etc...  Every test and even people who were "never wrong" told me my first was a girl - WRONG!  However I did crave different things with each pregnancy and I found my second one (a girl) made me a lot sicker and more tired in the first few months.

2)  I waited until the baby was showing as nine months is a long time!  Then we talked about it lots and what it would mean.  We read books.  WE bought the baby presents together and we also bought him presents from teh baby.  The only time it was an issue was when my husband was talking to my bump one day and said "it's your daddy here" - well, i think he thought he was going to lose both of us - so upset!  He was so excited when she came and the only time I found any jealousy was when I would sit to feed and he felt frustrated I couldn't be doing things with him.

3) I think your dr/midwife can tell from your tummy measurements once you are at a certain stage.  If it is still early an indication could be whether they can hear a heartbeat and whether you can feel movement.  Also, with both of mine nausea stopped pretty much exactly at 13 weeks - but that is not the same for everyone.

Sorry, can't help more with that one?

1.  Apparently, the sicker you get with morning sickness, the more likelihood there is of you carrying a girl.  Was told by a doctor who also specialises in pregnancy problems.  We are expecting our 5th daughter very soon, and I have been very sick with all of them, like 6 months of morning sickness!!!!!!!

2.  Tough one, but our 1 and 2 year olds have fun playing with my tummy, and while they do, I explain to them that there is a baby in there and that soon they are going to have another little sister.  I also got all my girls baby dolls and they have made the connection pretty quickly.

3.  Not accurately.  I'm in the same situation.  I can't remember exactly when my last period was, only that it was in September last year, but ultrasound says it had to have been in November, which isn't right.  Dating is never 100% accurate as all babies grow at different rates and they have times when they don't grow much at all, but are working on maturing other parts of themselves like organs.

Like the others said, there is really no good way to tell if you are having a boy or girl by how you are carrying, though may fun wives tales.  For how far along you are, you can only guess by when you first start to feel the baby, but that can be off by up to a month.  For some help with a letting your little one know about a new addition...This may help...

1st Q, no there isnt. I carried the same with both my kids and i have a girl and boy

2nd Q, I said to my son we were having a baby and it was a very special thing. I involved him with everything to all ultrasounds to getting bubs stuff ready and having him sit and feel my belly. naming the belly is good for bonding to. we knew we were having a girl and what her name was and Alex named her Cha Cha (Charlotte). They dont fully understand but the get the jist.

3rd Q, NO, NO, NO. no way in knowing at all. apart from having the doc feel about and a ultrasound. the pee test will tell you how much hormone is in it but not a date.

Ok well im no genius and im only going by my own pregnancy and other people i know. People who are having girls normally get bad morning sickness and it keeps up during the pregnancy. People who have boys may have a little morning sickness at the start or none. Im having a boy and had none but did feel sick, just didnt vomit. Same thing with my sister who had a boy. My other sister had 4girls and had morning sickness with all of them. Also im carrying just like my sister who had a boy and that is all baby. Although i have put on close to 20kgs!! you cant tell,a nd im just all baby and have put a little weight on my bum!

Ultrasound is the only other way to find out how far along you are. Its easier for them to tell the earlier in pregnancy you are cos most babies grow at the same rate at the start.

1: the only way to be certain is with an ultrasound or amniocentecis injection (this carries risks). Shape of belly isn't foolproof; I had a girl when I was expected to have a boy.

2: Tell them the truth in so far as they can understand it. ie you are growing them a baby brother or sister in your tummy. just as you grew them. It is best to involve them as much as possible; they are more likely to feel loving towards a baby sibling (rather than competitive with) that way. You will need to keep at it after bubs is born & be sure to give toddler plenty of attention too.

3: Not that I know of. An expert midwife may be able to guess vaguely but since size of growing babies vary enormously you won't get a date without professional help.

I suggest you either see the medicos or be prepared to be surprised about timing, gender & number of babies.

good luck

Q 2- talk to your toddler explain that her/she will be a big brother or sister, buy your toddler a doll even if it is a boy get them involved in setting up the babies room and picking outfits, when bubs is born you will prob still have problems I did my bubs was born 10 weeks ago and my boy is 11 years old we still had teething problems with him not being the only child anymore. hope thats helped

Sorry but I can only answer one question for you and that is the first one.   If you are carrying a boy (which I did) then you are more likely to be just all baby and carry from the front. 

If you are carrying a girl then you carry your baby all over, if that makes sense.  So you will be fatter in the hips and just generally more rounded.
