when should I drink coke or eat chocolate before today's scan?

[yellowflowers]

I have repeat 20 week scan today as last week they couldn't see everything they needed to because baby was in wrong position. They said I should have some coke or chocolate or sugar before this one to make sure it is awake and moving. Thing is they often run late - if I take sugary thing into waiting room with me and swig/eat it as I am called will that have enough time to work into my system? If I have too early presumably it will have worked through system before I get called if they are running late?

Why not have some before and some while you are waiting just to be on the safe side. :)

iirc ds and dd used to wriggle around most about 20 mins after eating something sugary.

I'd be tempted to constantly eat chocolate from now until your scan. What better excuse. :)

Sorry, no proper advice, just an idea.

hahaha - what brilliant ideas. [nips to corner shop]

I had a raspberry yoghurt ice cream while walking to my 20 week scan, so 30 mins before and the baby was doing the hoola if thats any help!
