20wk scan tomorrow!

[FTRsGotAShinyNewNN]

I am 20 + 5 with DC(2) and I have my anomaly scan tomorrow. DH is away in the armed forces and I'm taking DS(5.9) with me.
I plan to ask the sex during the scan and DS will come in for that bit (he'll wait outside with DM to begin with) DS is desperate for a baby sister and due to previous traumatic delivery I plan for this to be my last baby, how do I deal with gender disappointment in a 5 year old if he's getting a baby brother instead and knowing if that is the case there never will be a sister?
Any advice appreciated

Why would he come in for that bit?! Particularly if you're concerned that he might be disappointed. I think you should get some pictures and tell him the sex later on. Last thing you need during a scan is tears or tantrums from a child when you need to focus on what the sonographer is telling you about your second child.

He's very excited and I'm trying hard to keep him involved, we have talked about having a baby brother too and he's not necessarily been negative about a brother but he did tell me he'd wished for a baby sister on a wishing flower.
I don't think he'd be tears and tantrums I'd just like to know how to help him understand that it's ok to be disappointed but a brother will be nice too if that's what we get.

We booked a private gender scan so we could take ds as we thought he would be bored stiff at the length of a 20 week scan, we really wanted to know as he was adamant he wanted a brother and not a sister (his friends all have sisters so I think he wanted to be different) it is a boy and straight away he said 'I want a sister now'
I am sure at his age he will be fine. Ds is 4 and has asked a few times since the scan if we will have a girl one after the boy (it is a no due to medical reasons) he is fine with it.

Beforehand, tell him all the amazing things that a baby brother would bring (brotherly bond, telling him he'd be able to teach his brother all of the things he knows, maybe even ask him to help you pick a boys name etc). Don't focus on talking about a baby girl too much, as if it turns out your having a girl, I'm sure he'll be very happy anyway! But I agree maybe let him stay outside the room whilst having your scan, and if you find out your having a boy and your not ready to tell him straight away, you can maybe tell him later on when your ready. Good luck! X

How did you get on? x

Didn't manage to get back on last night but thank you for the responses.
The worry was all for naught, we're having a girl DS is very happy as are myself, DH and all of the family.
I think I'm mostly in shock I was really expecting a boy

Excellent congrats to you all

Congratulations!! Mine is tomorrow! how long did it take?

Wow congratulations!

Thank you all

MrsCK it actually took quite a while, 30-35 minutes maybe more, unfortunately DD was not very cooperative and the sonographer had quite a job trying to get a good view of the heart because baby was so wriggly. She only stated still right at the end

Ah fab thanks! just so I know what to expect!

Mrsck they normally say minimum 25 mins...mine last week was 55 mins and I have to go back this week as they couldn't get the heart measurements for me either!
